Keronite is a leading provider of Plasma Electrolytic Oxidation (PEO) surface treatment applications offering corrosion protection, wear resistance, thermal protection and electrical insulation for the defense, commercial aerospace and industrial vehicle markets, and also in semiconductor manufacturing. Keronite is expected to generate sales of approximately $9 million in 2022 and is expected to be neutral to Curtiss-Wright’s adjusted diluted earnings per share in its first full year of ownership, excluding first year purchase accounting costs, and produce a strong free cash flow conversion rate of approximately 100%. The acquired business will operate within Curtiss-Wright’s Aerospace & Industrial segment. “The acquisition of Keronite increases the breadth of our surface treatment services portfolio with unique and complementary coatings technologies recognized for their critical performance in severe service environments,” said Lynn M. Bamford, Chair and CEO of Curtiss-Wright Corporation. “The combination of this business with Curtiss-Wright’s long-standing customer relationships and global sales channels provides strong alignment to the strategic priorities as highlighted at our 2021 investor day and is expected to yield significant opportunities for long-term profitable growth.” Keronite’s PEO surface treatment process utilizes a bath-based method of producing ceramic layers on light alloys such as aluminum, magnesium and titanium to enhance their inherent performance characteristics. As the surface is oxidized, it incorporates an electrolyte thereby giving the coating specialized characteristics that are tailored to the specific application. Through Keronite’s process, lightweight metals are afforded the wear and performance properties of high-weight materials such as carbide or steel in a more environmentally-friendly manner, and are well-suited to support demanding applications such as aerospace or electric vehicle programs. ***Keronite, which was founded in 2000 and employs nearly 45 people, is based in Cambridge, UK**, **and also maintains operations in Greenwood, Indiana.*** **About Curtiss-Wright Corporation** Curtiss-Wright Corporation (NYSE:CW) is a global integrated business that provides highly engineered products, solutions and services mainly to Aerospace & Defense markets, as well as critical technologies in demanding Commercial Power, Process and Industrial markets.

Oxidation is the general chemical reaction of losing one or more electrons in an atom, molecule or ion, however, rust is an oxidation reaction only when iron reacts with water and oxygen. There are different colours of rusts and it’s important to know the difference so you can treat them correctly. ## Types of rust: ### Red Rust #### Hydrated oxide Fe2O3•H2O (high oxygen/water exposure) The most common type of corrosion is uniform corrosion. This is where an even layer of oxidation appears across the surface of the material. When metal is exposed to high volumes of water and oxygen, the iron oxidises with a contaminate, this creates “red” rust. ### Yellow Rust #### **Iron oxide-hydroxide FeO(OH)H2O (high moisture)** Yellow rust is present in metals that are found in large amounts of standing water. This type of rust is usually found in a solvated state, commonly found near sinks and bathtubs. ### Brown Rust #### **Oxide Fe2O3 (high oxygen/low moisture)** Brown rust can react even with lack of moisture, compared to the others highlighted above. Unlike red rust, brown rust can form as non-uniform corrosion, appearing on specific areas of the material rather than the overall surface. The manufacturing process can usually be the result of brown rust when contaminates are found on metal surfaces. ### Black Rust #### **Iron (II)oxide – Fe3O4 (limited oxygen)** Black rust can form when oxygen cannot reach the material, perhaps it is trapped and covered by another material resulting in a stain-like reaction. Unlike the other types of rust, black rust does not produce as quickly and is not as common which makes it easier to combat. ## **What happens when a material is not treated?** Premature failure can result in many problems; corrosion, stress corrosion cracking, galling amongst others. CWST provides a wide range of surface treatment services which can help to mitigate material oxidation and help to increase product life-span and reliability. #### **1) Thermal Plasma and HVOF Spray Coating** [HVOF spray coating and Thermal Plasma coatings](https://www.cwst.co.uk/home/services/engineered-coatings/thermal-plasma-and-hvof-spray-coatings/) are used commonly in the aerospace, automotive, power generation and oil and gas industries. This is due to the coatings ability to resist and present oxidation and erosion. There are a wide range of benefits to using Thermal Plasma and HVOF Spray coatings which you can find out more about by visiting our [material surface treatment page](https://www.cwst.co.uk/services/engineered-coatings/thermal-plasma-and-hvof-spray-coatings/). #### **2) Shot Peening** Component failure is often related to residual tensile stress induced during the manufacturing stage. Our controlled [shot peening](https://www.cwst.co.uk/home/shot-peening-or-laser-peening/) services are a highly cost-effective method to mitigate corrosion fatigue and wear.

Thermal spray coatings are typically used in the aerospace, automotive, power generation and oil and gas industries. Curtiss-Wright offers a wide variety of coatings including HVOF (High Velocity Oxygen Fuel), plasma, flame and arc spray coatings. The range of thermal spray coatings offered by CWST means that it’s possible to achieve a cost effective and high performing finish that protects metal components from heat, wear, corrosion, fatigue and oxidation. HVOF coatings are a viable alternative for hard chrome plating. Our thermal coatings can repair damaged and worn components- such as gas and steam turbines- to original specification. ## Types of thermal spray coating **HVOF** High velocity oxy fuel thermal coating is a process that propels semi-molten powders at supersonic velocity onto the substrate. The semi-molten powder then cools and solidifies in a fraction of a second to form a strong mechanical bond with the surface of the component. HVOF coatings tend to be extremely dense with low porosity, good thickness control and strong bond strength. **Plasma** The [plasma coating process involves spraying](https://www.cwst.co.uk/home/services/engineered-coatings/thermal-plasma-and-hvof-spray-coatings/) molten or semi-molten powders onto the surface of a component to provide a coating. The selected coating is injected in powder form into a high temperature plasma flame, where it is rapidly heated and propelled against the component surface using a carrier gas. Plasma sprayed coatings typically utilise higher temperatures and lower velocities (compared to HVOF) allowing a larger variety of coatings including ceramics to be applied. The component surface is usually roughed by grit blasting to provide a key for the coating. The hot material impacts on the roughened substrate where it cools rapidly shrinking against the roughened peaks of the surface forming a strong bond and foundation for the final coating. When this plasma spray coating process is carried out correctly is known as a “cold process” as the substrate temperature can be kept low during the process to avoid material damage. **Flame** Flame spray coating is widely considered the original method of thermal spraying and has been commonly used across a wide range of industries for over 100 years. The flame spraying process utilises an oxy-acetylene flame to apply the thermal coating. The heat from the flame melts the chosen coating material and compressed air propels it onto the product that is being coated. The flame spraying process is also another form of “cold process” due to the relatively low working temperature during the process. **Arc spray coating** The arc spray coating process provided by CWST is not only a cost effective and efficient service, but also a fast one. This type of thermal spray coating uses a twin wire feedstock that uses an electric arc to melt the feedstock and compressed air to propel the molten particles against the substrate. Arc wire coatings provide strong bond strength, low substrate temperatures and high coverage rates making them very suitable for large areas. There are many coating applications for this process (wear resistance, corrosion resistance, component repair and anti-fretting). This system also has the advantage of being portable and it can be used for on-site applications. ## Benefits of thermal spray coatings **Versatility in choice of performance enhancing coatings** Almost any material that melts and re-solidifies when cool can be applied as a thermal spray coating (pure metals, alloys, ceramics and carbides are amongst the most common). **Component protection** Coatings can be selected to:- Increase temperature tolerance (thermal barrier coatings – TBCs) Increase temperature conduction Increase resistance to wear (Hard face Coatings) Increase electrical conduction Increase electrical insulation Increase corrosion resistance Increase chemical resistance Increase resistance to fretting Provide accurate clearance control (abradable coatings) Metallisation of polymers and composites **Accurately controlled temperature of bulk substrate to 150°C or less** CWST has the ability to accurately control the temperature of the substrate during the coating process. -This prevents any change in the properties of the substrate and allows coating of low melting point polymers or composite materials. **Coating thickness is easily controlled** Matching optimum coating selection with robotic application the coating thicknesses can be accurately controlled to ensure that the optimum depositions are achieved. **Complex shapes can be coated** Even components with complex shaped surfaces can be coated effectively using robotically manipulated application of the thermal spray coating. **Excellent Coating Properties** The final coating is optimised using data from the lab; hot and cold mount of coating samples, micro-graph image analysis, tensile bond testing, hardness checking, surface finish checking, thickness and evenness checking. Pre and Post Processing CWST can offer pre-thermal spray services such as [shot peening](https://www.cwst.co.uk/home/shot-peening-or-laser-peening/) to manage residual stresses and improve fatigue life as well as post-thermal spray services such as liquid coatings, grinding, polishing and impregnation both internally and through a trusted network of processing partners. ## Find out more To find out more about Curtis Wright or the [thermal spray coating services](https://www.cwst.co.uk/services/engineered-coatings/thermal-plasma-and-hvof-spray-coatings/) provided by CWST [get in touch](https://www.cwst.co.uk/contact-us/) with a member of our skilled team today. ![author avatar](https://secure.gravatar.com/avatar/1a6b58bed8bdf1b25fb0eb00d35f3f764d46cacf52c57c485d40e1890d2e16ea?s=300&d=mm&r=g) generateuk [See Full Bio](https://www.cwst.co.uk/author/generateuk/) [ ](https://www.cwst.co.uk/author/generateuk/) **Categories:** News --- ### [Aero-Engine Component Failure Solutions](https://www.cwst.co.uk/aero-engine-component-failure-solutions/) **Published:** August 17, 2020 **Author:** generateuk **Content:** Aero engines are application-specific engines built to power an aircraft, however, given the strength and power of aero engines, they can sometimes also be used for other vehicles, in cases where a manufacturer’s design features high-performance specifications. Common [types of aero engines](https://www.aircraftcompare.com/blog/types-of-aircraft-engines/) include turboprop, turbojet, turboshaft, ramjet and turbofan engines. These forms of gas-powered engines have increased significantly since the 1900s and it is these technological advances that allow aero engineers to develop high-performance aircraft. However, recent advances in technology and materials have resulted in component specifications that must withstand more complex and hazardous product environments. Luckily, CWST’s material [coating and treatment services](https://www.cwst.co.uk/home/services/coating-services/) can help aero-engine manufacturers to ensure the highest quality and material endurance through our broad range of material solutions. **What is component failure?** Component failure generally occurs due to a sequence of events which as a direct result of design and the chosen materials to the chosen manufacturing process and component assembly. Processes such as heat application, welding, grinding, and machining during the manufacturing stage can cause component failure. Other aspects of manufacturing that can affect material performance and result in aero-engine component failure can include processes like bending, rolling, or forging. In-service conditions can also directly be attributed to component failure of a part such as volatile temperature change and environmental conditions, uneven high or low cyclic loads or stress profile, compression torsion and bending as well as foreign object damage. Matching the maintenance needs of the component to a products operating conditions and environment is crucial and the right surface treatment can dramatically extend the life of these critical parts. [***If you’re unsure which material treatment is best for your product, design or application, speak to us today to find out how we can help to reduce component failure***](https://www.cwst.co.uk/contact-us/)***.*** **Aero-Engine Failure modes** Although aero-engine failure modes are not limited to the below, some of the most common types of failure modes are: - Fretting - Galling - Fatigue - Contact fatigue - Fatigue - Corrosion - Stress corrosion cracking - Micro-cracking - Foreign object damage - Erosion - Water droplet erosion Aero-engine parts such as blade roots, airfoils, tie wire holes, propeller blades and turbine discs, blisks, and drums are susceptible to these failure modes due to their extreme product operating conditions and environment. **Aero-engine material failure mitigation solutions** CWST provide a wide range of material solutions that help to mitigate the common aero-engine failure modes above, this includes: - Controlled shot peening - Laser peening - A.S.E Isotropic peening - Thermal spray coatings [**Controlled Shot Peening**](https://www.cwst.co.uk/services/controlled-shot-peening/) Known as a cold working process, the shot peening process is applied using spherical media know as shot. As each piece of media hits the surface of the material it creates a tiny indentation where the surface will attempt to yield but is restrained by the substrate material. This combination of forces causes the substrate material to compress creating a beneficial compressive residual stress which leaves the surface material resistant to crack initiation and propagation whilst also removing any tensile stresses as a result of manufacturing. [***Find out more about controlled shot peening: “Could your components be improved by Shot Peening?”***](https://www.cwst.co.uk/could-your-components-be-improved-by-shot-peening/) [**Laser Peening**](https://www.cwst.co.uk/services/laser-peening/) The process of laser peening can place exceptionally deep residual compressive stress into key areas of a product to retard crack initiation and growth enabling increased fatigue strength ratings. Laser peening is not a replacement process for controlled shot peening but has additional advantages that can influence which method is best for any given application. [**C.A.S.E Isotropic Peening**](https://www.cwst.co.uk/services/c-a-s-e-vibratory-and-isotropic-super-finishing/) The technique of C.A.S.E ™ isotropic superfinishing has been developed as a metal surface treatment that provides components with excellent bending and contact fatigue strength with resistance to high loading. C.A.S.E ™ (Chemically Assisted Surface Enhancement) is also sometimes referred to as isotropic finishing. Isotropic finishing is a material treatment solution where a product is first shot-peened followed by chemical surface treatment where any mental asperities are gently removed, retaining valleys for optimum oil retention.

However, in short, the biggest benefit of engineered coating is that it extends the component lifetime.[![How Engineered Coating Extend Component Lifetime - CWST](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2019/09/CWST-1-300x200.jpg?strip=all "CWST 1 | CURTISS-WRIGHT SURFACE TECHNOLOGIES")](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2019/09/CWST-1.jpg?strip=all&w=2560) At Curtiss-Wright, we work with a number of industries including aerospace, oil and gas, automotive, medical and general industrial markets, so ensuring components have their fullest life span is very important. Our range of engineered [coatings protect against adverse environmental and service](https://www.cwst.co.uk/home/services/coating-services/) conditions, preventing friction, improving lubrication and reducing noise. Our range of industrial engineered coatings include: • Thermal spray – providing thermal management, corrosion and erosion, [component protection and repair](https://www.cwst.co.uk/cwsts-onsite-component-repair-and-overhaul-services/) of turbine components (including high velocity oxy fuel, flame spray, arc and diffusion. • Solid film lubricant and liquid component coatings – long lasting lubrication in harsh operating conditions and to prevent friction and galling (including Everlube, PTFE, zine rich, impingement, Teflon, Primers and more) • Parylene conformal coatings – biocompatible, ultra thin coating used to reduce friction and protect components from the environment, commonly used for medical devices and electronic applications (including Parylene C and Parylene N) [![Engineered Coating Extend Component Lifetime](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2019/09/CWST-2-300x200.jpg?strip=all " | CURTISS-WRIGHT SURFACE TECHNOLOGIES")](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2019/09/CWST-2.jpg?strip=all&w=2560) The way our engineered coatings work is simply by fortifying the surface of metals and other substrates – transforming your inexpensive components and parts into super hard, dry lubricated and chemical resistant components. This in turn ensures your components last longer, and is more cost effective than buying expensive components. It is also more environmentally friendly to reuse old materials and components. As said before, the goal of engineered coatings is to enhance the surfaces of components, imparting performance attributes such as corrosion resistance, hardness and dry lubrication. Surface-enhancing coatings are used to transform inexpensive metal parts into chemical resistant, super hard, dry-lubricated components that last longer and perform better than parts made of expensive and rare metals. Engineered to withstand the harshest of environments. Coatings are applied to components using an orderly process that begins with a thorough cleaning. Next, applying a coating layer using conversion, deposition, thermal spray or a mix of these techniques enhances the surface. The process continues with a controlled infusion of engineered polymers or other dry-lubricating particles or metals. The biggest advantage of engineered coatings compared to other options, such as paint-on varieties or black oxide, is that the particles in the engineered coatings become part of the surface. Particles are mechanically bonded and the resulting surface layer cannot chip, flake, peel or rub off. A variety of engineered coating systems are available, each designed and tested to protect a certain metal or to solve a common problem. **[Contact](https://www.cwst.co.uk/contact-us/)** the team at CWST to explore our range of Metal Surface Finishing Treatment Processes, we will help you discover which of our specialist treatment is right for your components. ![author avatar](https://secure.gravatar.com/avatar/1a6b58bed8bdf1b25fb0eb00d35f3f764d46cacf52c57c485d40e1890d2e16ea?s=300&d=mm&r=g) generateuk [See Full Bio](https://www.cwst.co.uk/author/generateuk/) [ ](https://www.cwst.co.uk/author/generateuk/) **Categories:** News --- ### [Curtiss-Wright Acquires F.W.

Since this time, laser peening (or LSP) technology has seen developments that have resulted in decreased costs as well as increased throughput. Laser Peening is a surface engineering process that places deep residual compressive stress into key areas of a component. This process increases the resistance of materials to surface-related failures. Laser peening can also be used to strengthen thin sections of a component or harden a surface as well breaking up hard materials. The [laser peen or laser shock peening](https://www.cwst.co.uk/home/services/laser-peening/) process does not utilise the thermal effects of a laser, instead it uses the dynamic mechanical effects of a shockwave that is imparted by a laser to modify the surface layer of a target material. Laser peening is being used to prolong the fatigue life of critical aerospace components such as turbine engines and aircraft structures as well as for wing skins to achieve the requirements of the new generation of intercontinental aircraft. Other potential applications of LSP forming have also emerged for the automotive, power generation, nuclear waste disposal, drilling, medical implants and recreational sports. The process of laser peening means that component materials have a deeper residual compressive stress which enables an increased resistance to low cycle, high stress situations (LCF) as well as high cycle, low stress situations (HCF) in a deteriorating surface environment. LSP also helps to combat material erosion, strike damage, fretting and corrosion. In addition, the laser peen process allows for less cold work enabling greater retention of residual compressive stress in high load and/ or thermally challenging conditions. What’s more, there is no process contamination and original surface finish and topography is easily maintained and controlled through a high precision process and quality control. Curtiss-Wright specialise in surface technologies and offer customer a single source solution and point of contact for all their controlled metal surface treatments, supporting their requirements through a global network of over 70 worldwide and on-site field teams.

But what does this really mean, and what are the different metal surface treatments we provide? Simply, that we have vast knowledge in a range of industrial processes that alter the surface of metal to achieve a certain property, for example, to improve appearance, adhesion, corrosion resistance, hardness and much more. Our metal surface treatments can be categorised by how they affect the subject, either removing/reshaping the finishing, or adding/altering the finishing. ## What metal surface treatments do we provide? At CWST we offer a wide variety of key metal surface treatments, finishes and processes. Each surface finishing process increases performance and life of metal components by protecting against premature failure, due to fatigue, corrosion, stress, fretting, friction and galling, as well as support against environmental and thermal variation. Our high-performance metal surface finishing treatments include the following. ### **Controlled Shot Peening** Tensile stresses induced during welding, grinding, machining and heat treatment are replaced with beneficial compressive stresses proven to prevent fatigue and stress corrosion cracking. This cold working process is applied using spherical media known as ‘shot’, as each piece hits the surface it creates an indentation where the surface will attempt to yield but is restrained by the substrate material. This in turn causes the material to compress, creating added stress – making the surface crack resistant and removes any prior manufacturing tensile stress. Find out more about **[Controlled Shot Peening](https://www.cwst.co.uk/services/controlled-shot-peening/)**. [![Controlled Shot Peening - CWST ](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2019/07/Controlled-Shot-Peening-300x209.png?strip=all "Controlled Shot Peening | CURTISS-WRIGHT SURFACE TECHNOLOGIES")](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2019/07/Controlled-Shot-Peening.png?strip=all&w=2560) ### **Shot Peen Forming** This surface treatment creates curvature in aircraft wing skins to enhance lift and efficiency and to protect against fatigue. Shot peen forming is also used to correct the distortion of components following manufacturing. Within this process, control spherical media is fired at the surface, creating indentations causing the material to elastically stretch, however it is restrained by the substrate. This causes the surface to arc towards the peened side, resulting in curvature. This metal surface treatment method can induce stress to greater depths, with a tighter radius of curvature as well as being able to be performed on thicker materials. Find out more about **[Shot Peen Forming](https://www.cwst.co.uk/services/shot-peen-forming/)**. ### **Laser Peening** Laser peening induces compressive stress with precision accuracy into key areas of a component up to 5 to 10 times deeper than other conventional cold working techniques. This metal surface treatment uses an output beam at 25 joules at 18 nanoseconds from a glass laser, a thin stream of water is made to flow across the surface and the laser transparently passes through the water, and a pulse is absorbed on the metal surface. The rise in pressure creates a shock wave that penetrates into the metal, straining the surface layer.

Isotropic Finishing Super Finishing** Removes surface asperities to create a mirror like finish, reducing macro and micro-pitting, oil temperature and noise whilst promoting lubricant retention. This surface treatment uses controlled [shot peening,](https://www.cwst.co.uk/home/shot-peening-or-laser-peening/) followed by chemical surface superfinishing. This removes any metal asperities, creating a surface with a negative skew (Rsk) retaining valleys for optimum oil retention, reducing surface friction and operating temperatures.

This coating process uses a heated powder or feedstock which is propelled at high velocity, using kinetic energy formed from a gas stream, onto the surface. This forms a mechanical bond with the substrate as it cools – building up thickness and density.

Typically, dry-film lubricants will be used when other lubricants such as grease and oil cannot be used due to temperature load, wear, migration and debris. In these conditions, traditional lubricants like oil or grease can undergo a state change and no longer provide protection, however, a dry-film lubricant will remain intact and provide continuous lubrication and protection. ## **What are dry film lubricants?** Primarily, there are two main types of dry-film lubricants, which are known as crystalline lattice (lamella) type structures such as Molybdenum Disulphide, Tungsten Disulphide and Graphite and Fluorocarbons such as PTFE. In crystalline form structures such as Molybdenum (MoS2), the shear forces between opposing layers are weak resulting in lubricity between sliding surfaces. There are several factors for PTFE coatings that define dry-film lubricants; firstly, the ability to resist attack from another chemical structure, secondly its bond strength, and lastly its ability to repeal other atoms which in combination gives PTFE coatings their ultra-low coefficient of friction and excellent chemical resistance. ## **What are dry film lubricants used for?** There is a wide variety of typical applications of dry-film coatings, some of which include: - Fasteners, springs bearings, cams, gears and seals - Aerospace hydraulic fittings, valve components and non-intrusive medical instruments - Shafts, splines and bushes - Rubber and other non-metallic substrates - Saw blades and secateurs - Automotive fasteners, seat slides and rails - Petrochemical, oil and gas subsea and topside components Dry-film lubricants are useful in conditions where conventional lubricants are inadequate. One such example is where reciprocating motion is present. A standard application of dry-film lubricant could include where a sliding or reciprocating motion that requires lubrication to minimise wear is present. An example of this use case can be seen in gear and change lubrication. Liquid lubricants will squeeze out while solid lubricants will not escape interlocking or reciprocating parts. Dry-film lubricants can also be used in ceramic applications for cases where chemically active lubricant additives have not been found for a particular surface, such as polymers or ceramics. Also, the benefits of dry-film lubricants can be applied to instances where lubrication is required in a high-temperature environment or where there is an oxidising atmosphere. Liquid lubricants such as oil and grease will typically not survive these conditions. Furthermore, where extreme contact pressures are present, dry-film lubricant provides a high bearing-load combined with a low shear stress due to the lamellar structure of the lubricant. ## **Application methods** Dry-film lubricants can be applied in a wide variety of methods to best suit the work-piece application and environment. - Free powders - Anti-frication coatings - Spraying/ dipping/ brushing - Composites CWST has a proud history that dates back to 1920 when the Wright Brothers and Glen Curtiss founded the Curtiss-Wright Corporation.

But consider what happens should one of these parts fail. Lengthy downtime, potentially hefty shipping costs and loss of income could be just a few of problems you may face when it comes to component failure. To prolong the life of important components and equipment we recommend reducing failure by considering different material treatments. **What are the biggest factors in component failure?** There are many different factors which can be involved when it comes to component failure. There are common issues such as oxidation and rust. Other reasons for component failure can also include tensile stress or fatigue. At CWST, we diagnose the problem and find a solution with our extensive range of life extending material treatments. Discover some of the most common issues which can cause component failure, that we can help to prevent or fix: - Fatigue - Fretting fatigue - Cavitation corrosion - Forming or correcting the shape of distorted components - Stress corrosion cracking - Corrosion generally - Exfoliation corrosion - Filiform corrosion **What are material treatments and how do they prevent failure?** There are several types of material treatments to help prolong the life of critical components within powertrain and drivetrain industry. The general purpose of a material treatment is to protect and strengthen the material to avoid failure mechanisms such as stress corrosion cracking and surface wear. By applying a treatment to the surface, you can strengthen and protect the component meaning that it will be able to withstand higher hertzian and contact pressure, heat and tensile stresses along with exposure to harsh operating environments. You can also help to reduce the risk of oxidation, wear, micro pitting, and premature failure which can easily affect certain materials. One material treatment which will help your crankshafts, camshafts, axels and other components withstand higher loads, operating temperatures and protect against wear for a prolonged period of time is [thermal spray coating](https://www.cwst.co.uk/services/engineered-coatings/thermal-plasma-and-hvof-spray-coatings/). But whichever option you choose, all these material treatments will help prolong the life of your components and avoid problems that can be detrimental to your business. **How do I know which surface treatments will provide the most cost-effective and beneficial results for my critical powertrain and drivetrain components?** Here at CWST, we understand the importance of extending the life and durability of components and structures. CWST can call upon many years’ experience, data and case studies to assist in not only solving post machining and processing problems but also by helping at the design stage. We can assist in areas such as weight saving and strength enhancements, providing wear and fatigue resistant treatments allowing for the use of lower cost base materials. These specialised services and processes can be carried out within our worldwide network of facilities and we can even provide some services onsite in customer locations or out in the field.

Jason Delaney the Galway Technical Sales Manager presented at the conference on the topic of ‘Parylene Coatings – Green Chemistry reducing friction and protecting biomaterials and medical devices’. The presentation was well received with many interesting questions and discussions after and we have included someof the questions raised below: ***Can Parylene provide microbial protection for implant devices?*** Parylene C is commonly used in implant devices, while it does not encourage bacterial growth, in that it acts as a restrictive coating for cell adhesion, it is not anti-microbial. There are anti-microbial variants of Parylene on the market however these are new and untested for implant devices. ***Can Parylene be used on any surface, metal, plastic or elastomer?*** Yes, we work with many different substrates to great success. Specific surface preparation requirements are needed in some cases to ensure good adhesion so we always treat each new project with fresh eyes, applying the experience and expertise of our process engineering team to ensure the most effective results. ***How can pin hole free coverage be ensured on a surface?*** Once the product is appropriately prepared and the coating is above 0.6µm the process of application itself ensures pin hole free coverage. The monomer is like a fog in the deposition chamber and as it forms into a polymer any and all exposed surfaces will be coated in a conformal manner, this includes the chamber as well as the product. Florescence have been used to ensure the coating is 100%. This is a two step process where the product is coated in Parylene then the Parylene in the florescent. Then using a black light any voids will show up. This has been used mainly in military electronic applications. However once they realise that a void will not occur where the process has been optimised this secondary stage becomes unnecessary and is usually abandoned. ***How does Parylene differ from PTFE as a coating to reduce friction?*** In terms for co-efficient of friction Parylene N (0.25 static and dynamic) performs as good as many PTFE coatings sitting in the middle of the range of performance. As a soft polymer Parylene does not produce particulate that has been associated with PTFE coatings and a topic of concern for the FDA. As it does not chip or flake Parylene can be higher yielding / reusable for many manufacturing aid applications so can also reduce cost in many cases as a replacement to PTFE mandrels. ![Medtec UK 2014](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/IMG_3157_000.jpg?strip=all "Medtec UK 2014 | CURTISS-WRIGHT SURFACE TECHNOLOGIES") Please [contact us](https://www.cwst.co.uk/contact-us/) for more details about upcoming events or to find out more about our services and applications. ![author avatar](https://secure.gravatar.com/avatar/1a6b58bed8bdf1b25fb0eb00d35f3f764d46cacf52c57c485d40e1890d2e16ea?s=300&d=mm&r=g) generateuk [See Full Bio](https://www.cwst.co.uk/author/generateuk/) [ ](https://www.cwst.co.uk/author/generateuk/) **Categories:** Archived News, News --- ### [CWST at the 2014 MACH Exhibition](https://www.cwst.co.uk/news-mach-exhibition-2014/) **Published:** April 13, 2014 **Author:** generateuk **Content:** The MACH exhibition is the UK’s largest manufacturing technologies event and features cutting edge companies and innovative products and naturally CWST attended.

The process of controlled shot peening helps to reduce and prevent fatigue and stress corrosion failures and prolong product life. Small spherical balls (known as media) are fired at the surface of a component. This process helps to reduce component failure as result of residual tensile stress induced during manufacturing. Furthermore, some residual tensile stress could be induced during operating conditions and the process of controlled shot peening can help to reduce or remove this. The process of controlled shot peening involves the use of spherical media known as shot. As each piece of shot strikes the surface of a material it creates a small indentation where the surface will attempt to yield. Substrate material will restrain the surface under compression during this process- removing tensile stresses. At CWST, computer controlled robotic machinery is used during controlled shot peening to maximise precision and quality. Each application of controlled shot peening has its own unique requirements such as geometry, manufacturing method, base material, strain sensitivity, in-service environment and loading conditions. Further considerations such as cost and turnaround time will also be considered for each application. The Shot Peening Process is one of the most economical and effective methods of both increasing surface and subsurface residual compressive stresses and removing residual tensile stresses to increase the components life. Depending on the application of the component, different media may be used. Media range from metal, ceramic and glass and will each will be used for different material finishes and applications. Common applications of controlled shot peening include; gear parts, camshafts, clutch springs, coil springs, connecting rods, crankshafts, gearwheels, leaf and suspension springs, rock drills and turbine blades. The shot peening process is also sometimes used in aviation and automotive industries on components like engine blocks and cylinder heads. Controlled shot peening is a highly cost-effective method of reducing residual tensile stress that may have been induced during manufacturing or the operating conditions of components. Furthermore, controlled shot peening helps to prevent failures due to; metal fatigue, corrosion fatigue, stress corrosion cracking, intergranular corrosion, fretting, falling, spalling and wear. Curtiss-Wright specialise in surface technologies and offer customer a single source solution and point of contact for all their controlled metal surface treatments, supporting their requirements through a global network of over 70 worldwide and on-site field teams.

The earliest example of this process can be traced back to a gold helmet circa 2700 B.C. In addition to shaping, cold hammering was also used to strengthen metals and was widely used in producing the final shape and hardness of armour during the crusades (1100-1400 A.D.). During the 11th Century the sword makers of Toledo produced a sword so superior to any other that they became highly prized and sought after. As well as lightweight, it was very strong and held a sharp edge and could also be bent almost double over and over without breaking. Naturally these blacksmiths would not have known that the hammering also introduced a residual compressive stress which contributed to its strength The process remained relatively unchanged until the industrial revolution when there were many experiments on the manipulation of metals, usually termed as “cold rolling”. This essentially replaced cold hammering and through trial and error brought about improvements in surface hardness and fatigue life. During the 1920’s the benefits of mechanical pre-stressing were more understood and A C Sampietro, a renowned automotive engineer, was reputed to have said that fillets of crankshafts in European race cars were hand peened to improve fatigue life. The earliest published work on shot peening was by E G Herbert in March 1927, where he wrote an article on “work-hardening of steel by abrasion”, this was followed by an article published by Mr O Poppl in April 1929 citing an experiment on five fatigue specimens which were partially peened. Of the five – four of these broke in the non-peened area under fatigue loading, but in the areas that were peened, there was no detrimental effect or fatigue. This proved that by using peening fatigue life could be improved. After much research the question of when and how the process of shot peening was formally discovered appears to have been between 1927 and 1929, with the automotive industry taking a further lead by introducing it into their specification for the manufacture of the Cadillac Valve springs in December 1929. The process of controlled shot peening continues to be developed and improved as new materials emerge and change with the introduction of specifically designed robotic equipment and advances in material testing and analytical services. ![author avatar](https://secure.gravatar.com/avatar/1a6b58bed8bdf1b25fb0eb00d35f3f764d46cacf52c57c485d40e1890d2e16ea?s=300&d=mm&r=g) generateuk [See Full Bio](https://www.cwst.co.uk/author/generateuk/) [ ](https://www.cwst.co.uk/author/generateuk/) **Categories:** News, Technical --- ### [MACH Show 2016, Birmingham](https://www.cwst.co.uk/mach-show-2016-birmingham/) **Published:** March 11, 2016 **Author:** generateuk **Content:** Curtiss-Wright Surface Technologies will be exhibiting at the MACH Show at the NEC in Birmingham from 11th to 15th April 2016.

It is a process for increasing the life, strength and performance of metal parts, but why and how? ## What does Shot Peening Do? [![what is shot peening?](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/10/what-is-shot-peening-300x194.jpg?strip=all "what-is-shot-peening | CURTISS-WRIGHT SURFACE TECHNOLOGIES")](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/10/what-is-shot-peening.jpg?strip=all&w=2560)Controlled shot peening creates an area of compressive stress which is resistant to fatigue and stress corrosion cracking. The compressive stress replaces any residual stresses that may have been introduced during manufacturing and by external applied stresses such as bending load, torsional load and pressure load. If shot peening is introduced as part of the manufacturing process, significant improvements in life and performance can be realised. Fatigue resulting from residual and applied stresses, together with stress corrosion is reduced by shot peening. Shot peening is a cost effective treatment which can be performed on components of any shape and size and also [on-site](http://www.metalimprovement.co.uk/on-site-processing.html) for large or fixed equipment. When combined with reduced maintenance costs achieved by extended part life, you can clearly see why leading manufacturers include this process in their specifications. ## What is the process of Shot Peening? Shot peening is still a cold working process where small spherical media called shot strikes the surface creating a small indentation. In order for the indentation to appear the surface layer must yield in tension. However, the compressed material grains try to restore the original shape which produces an area of compression. Continual coverage forms a uniform layer of residual compressive stress. Cracks will not occur in a compressively stressed area.

Recently our UK [E/M Coatings Division](http://www.emcoatingsuk.co.uk/) also completed work on 30 different structural parts and these aluminium components will form part of the bonded framework of the car, providing both strength and rigidity. What is the [**BLOODHOUND SSC project**](http://www.bloodhoundssc.com/)**?** The Bloodhound initiative was launched on the 28th October 2008 at the Science Museum in London. The team, including Richard Noble OBE and Wing Commander Andy Green, announced their intention to build a car capable of breaking the World Land Speed Record. They hoped that by launching such an iconic project, it would inspire a new generation of Scientists and Engineers and involve Companies from across the UK and the World in the development of the car itself. The hope is that the supersonic car will reach its intended target speed of 1000mph, a figure suggested by Ron Ayer who broke the Diesel World Land Speed Record in 2006. Interestingly the Bloodhound project name was inspired by Ron Ayer’s missile – Bristol Bloodhound 2. Being part of Curtiss-Wright Surface Technologies we have a long history in setting records as evidenced by our founders Glenn Curtiss and the Wright brothers who undertook the first recognised flight in 1903. This was subsequently followed by Glenn Curtiss in 1907, who by riding his Curtiss V-8 powered motorcycle at a speed of 136.4 mph, became the “fastest man in the world”, closely followed a year later by achieving the same feat in the air with a speed record of 46.5 mph.

Dry film lubricant coatings have different properties depending on their structure and composition. These properties can be for high load bearing, very low coefficient of friction, high temperature and also increased resistance to chemical attack, abrasion and corrosion. The Everlube® coatings range includes environmentally friendly and REACH compliant coatings as well as air cured, high temperature and PTFE. In addition to the Everlube® coatings range other leading product brands include Lube-Lok®, Lubri-Bond®, Ecoalube®, Ever-Slik®, Esnalube™, Perma-Slik®, Electrobond®, Formkote® and Henco-Mask™. ## **When are dry film lubricants like Everlube**® **coatings used** Dry film lubricants are often used when other lubricants such as grease and oil cannot be used due to temperature load, wear, migration and debris when the liquid can change fluid state and will no longer provide protection. In these conditions a dry film lubricant will remain intact and provide continuous lubrication. ## How do dry film lubricants work[![Everlube coating diagram](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/08/Crystalline-lattice-diagram-226x300.jpg?strip=all "Crystalline lattice diagram | CURTISS-WRIGHT SURFACE TECHNOLOGIES")](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/08/Crystalline-lattice-diagram.jpg?strip=all&w=2560) There are two main categories of dry film lubricants which are crystalline lattice (lamella) type structures such as Molybdenum Disulphide, Tungsten Disulphide and Graphite and Fluorocarbons such as PTFE. For crystalline type structures such as Molybdenum Disulphide (MoS2), the shear forces between the layers are weak resulting in lubricity between the sliding surfaces. The key factors for PTFE coatings are firstly its ability to resist attack from another chemical structure, secondly its bond strength and thirdly its ability to repeal other atoms which in combination gives PTFE coatings their ultra-low coefficient of friction and excellent chemical resistance. ## Typical applications of Everlube® coatings - Fasteners, springs, bearings, cams, gears and seals - Aerospace hydraulic fittings, valve components and non-intrusive medical instruments - Shafts, splines and bushes - Rubber and other non-metallic substrates - Saw blades and secateurs - Automotive fasteners, seat slides and rails - Petrochemical, oil and gas subsea and topside components ## Technical Data Sheets [Download Ecoalube 643 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Ecoalube-643-TDS.pdf) [Download Esnalube 382 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Esnalube-382-TDS.pdf) [Download Everlube 10027 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everlube-10027-TDS.pdf) [Download Everlube 10047 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everlube-10047-TDS.pdf) [Download Everlube 1150 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everlube-1150-TDS.pdf) [Download Everlube 1155 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everlube-1155-TDS.pdf) [Download Everlube 1170 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everlube-1170-TDS.pdf) [Download Everlube 1180 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everlube-1180-TDS.pdf) [Download Everlube 1186 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everlube-1186-TDS.pdf) [Download Everlube 1PX1 RFS →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everlube-1PX1-RFS-TDS.pdf) [Download Everlube 1PX1 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everlube-1PX1-TDS.pdf) [Download Everlube 6102G →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everlube-6102G-TDS.pdf) [Download Everlube 6108 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everlube-6108-TDS.pdf) [Download Everlube 6111 →](https://www.cwst.co.uk/wp-content/uploads/2026/02/Everlube-6111-TDS.pdf) [Download Everlube 6150 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everlube-6150-TDS.pdf) [Download Everlube 6155 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everlube-6155-TDS.pdf) [Download Everlube 620 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everlube-620-TDS.pdf) [Download Everlube 620A →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everlube-620A-TDS.pdf) [Download Everlube 620C →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everlube-620C-TDS.pdf) [Download Everlube 626 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everlube-626-TDS.pdf) [Download Everlube 732 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everlube-732-TDS.pdf) [Download Everlube 853 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everlube-853-TDS.pdf) [Download Everlube 9002 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everlube-9002-TDS.pdf) [Download Everlube 9005 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everlube-9005-TDS.pdf) [Download Everlube R75 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everlube-R75-TDS.pdf) [Download Everslik 1201 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everslik-1201-TDS.pdf) [Download Everslik 1301 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Everslik-1301-TDS.pdf) [Download Flurene 177 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Flurene-177-TDS.pdf) [Download Flurene 199 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Flurene-199-TDS.pdf) [Download Flurene 611 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Flurene-611-TDS.pdf) [Download Formkote T50 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/Formkote-T50-TDS.pdf) [Download LubeLok 5396 →](https://www.cwst.co.uk/wp-content/uploads/2025/08/LubeLok-5396-TDS.pdf) [Download LubeLok 77S →](https://www.cwst.co.uk/wp-content/uploads/2025/08/LubeLok-77S-TDS.pdf) --- ### [Controlled Metal Surface Treatment Literature](https://www.cwst.co.uk/home/downloads/literature/) **Published:** August 20, 2015 **Author:** cwst_user **Content:** Curtiss-Wright Surface Technologies has produced a wide range of leaflets and technical articles to provide full information in detail for all our surface treatment products and services which you are welcome to download.

Gentle curves within the elastic range of the material are regularly formed to consistent tolerances.** Varying curvature requirements, material thickness, cut outs, reinforcements and pre-existing distortion can all be processed with Shot Peen Forming. ## Shot peen forming process According to a predetermined specification, media is fired at the surface creating indentations in the surface. Each indentation causes the material to elastically stretch but is restrained by the substrate. The surface will bend or ‘arc’ towards the peened side and the resulting curvature will force the lower surface into a compressive state. This controlled process enables the surface to be manipulated into the desired and sometimes complex contours. Laser peening is an alternative technique for the introduction of residual compressive stresses. It has the advantage over conventional [shot peening](https://www.cwst.co.uk/home/shot-peening-or-laser-peening/) in that it induces these stresses to greater depths, consequently a tighter radius of curvature can be achieved or performed on thicker materials. Parts formed by peen forming exhibit increased resistance to flexural bending fatigue and where peen formed pieces are processed on one side only, the result causes both sides to have compressive stress. These compressive stresses serve to inhibit stress corrosion cracking and to improve fatigue resistance. Shot peen forming is the preferred method of forming aerodynamic contours for aircraft wing skins. It is a dieless forming process that is performed at room temperature and it is best suited for forming curvatures where the radii are within the elastic range of the metal without abrupt changes in contour. 3D Computer modelling techniques based on the degree of compound curvature will calculate and illustrate the degree of peen forming required. ## Correction of distortion A very successful method of correcting distortion caused during manufacturing for example through casting, rolling, forging and heat treatment, is using controlled [shot peening](https://www.cwst.co.uk/shot-peening-what-is-it-and-how-does-it-work/) to stretch the material on the concave side of the distorted component to bring the component back to pre-manufacture specification. --- ### [Peentex Surface Engineering and Architectural Finishing](https://www.cwst.co.uk/home/services/surface-texturing-and-architectural-finishes/) **Published:** August 20, 2015 **Author:** cwst_user **Content:** **Peentex is a decorative textured architectural finish applied by controlled shot peening which can be used for architectural finishing’s on metal, glass, wood and acrylic** Controlled shot peening has long been associated with engineered surface finishing of metals including steels, stainless steels, aluminium, titanium and copper alloys. It forms an essential part of the manufacturing process used within the engineering industry to improve wear and corrosion resistance and prevent premature fatigue failures. We are able to accurately control and repeat the peening process to produce a range of different textures and engineered surface finishes creating highly decorative designs and finishes. Peentex surface texturing also has practical uses for high traffic areas as the finish diffuses direct light and glare disguising fingerprints and mild blemishes as well as giving a higher degree of wear and damage tolerance. It is also non-directional so ideally suited for welded joint and frames, giving the weld bead a more uniform appearance. --- ### [Peenflex Protective Coating, Moulding and Masking](https://www.cwst.co.uk/home/services/protective-moulding-and-masking/) **Published:** August 20, 2015 **Author:** cwst_user **Content:** Our protective mouldings and maskings are damage and abrasion resistant – a simple but cost effective solution which will protect sensitive areas of metal components through the various stages of processing, lifting, moving, storage and despatch. Developed to protect critical components during our own processing we have now extended this service and produce protective mouldings and coatings directly for our customers. Using our knowledge and experience, we are able to assess component requirements to produce protective mouldings and maskings to meet customers’ specific needs and reduce unnecessary costs resulting from damage, delays and rework. All our protective mouldings and maskings are rigorously tested to ensure a high quality of wear resistance enabling them to be recycled many times through the handling stages, and presenting a cost effective solution to damage prevention. ## Typical applications of protective mouldings - Masking of sensitive parts during peening, blasting and coating processes - Creating wear-resistant inserts to reduce the cost of tooling replacement - Casting onto lifting equipment to prevent common damage - Close protection of sensitive inspection equipment, tooling, gauges, expensive cutting tools and masters - Repairs to existing mouldings - Replacements for high value components made from similar materials - Bonding to wheels, rollers and plates --- ### [Onsite Spraying, Component Repair and Overhaul Services](https://www.cwst.co.uk/home/services/onsite-services/) **Published:** August 20, 2015 **Author:** cwst_user **Content:** **Our on-site spraying and component coating and repair services are suited to the processing of plant equipment which cannot be moved due to size or fixed installation. Our customers are typically in the aerospace, oil, gas, chemical and power generation industries covering MRO work for example aircraft and steam turbine repairs but also welded structures such as bridges, storage vessels and damaged street furniture and other architectural applications. In addition processing plants such as steel and paper mills, mining facilities and food processing.** Our experienced component repair crews will meet the same stringent quality approvals and procedures followed in our own finishing process facilities to meet our customer’s industry specifications, minimizing down time, reducing maintenance, logistic and shipping costs for oversize equipment. Our people can be mobilised at short notice anywhere worldwide. ## Typical component repairs services for on-site work include: - Fatigue - Fretting fatigue - Cavitation corrosion - Forming or correcting shape of distorted components - Stress corrosion cracking - Corrosion generally - Exfoliation corrosion - Filiform corrosion ## Metal Surface Treatments used for on-site repairs ### Controlled shot peening Controlled Shot Peening re-introduces beneficial residual compressive stresses lost through corrosion, erosion, wear and potentially thermal or stress overload. In these situations it is necessary to re-introduce those beneficial stresses in the same manner as initially applied to ensure identical performance. Sometimes it is necessary to repeat processing as initially applied via fully mechanised or even robotic processing – all within the capability of Curtiss-Wright Surface Technologies. ### Controlled search peeningSM Developed from controlled [shot peening,](https://www.cwst.co.uk/shot-peening-what-is-it-and-how-does-it-work/) this process searches for sub-surface exfoliation, exposing structures with reduced strength by inducing surface compressive stresses. This stretches and yields the outer material and any visible blistering and flaking at the surface indicate the existence of exfoliation corrosion that is selectively attacking the aluminium substrate via the grain boundaries. Dressing to remove exfoliation and subsequent inspection with search peening again may reveal further fresh areas of exfoliation and/or other visible surface corrosion which may require repeated processing. It is essential that after any corrosion removal and blending that beneficial compressive stresses are restored to the component by controlled peening. ### Flapper or roto peening This process is a highly effective, clean and a quick alternative to controlled shot peening used after blending to restore the beneficial compressive stresses. Components can be treated in situ and no masking is required making it ideal for small areas of repair in critical components reducing maintenance costs and downtime. It is not as effective as controlled [shot peening](https://www.cwst.co.uk/home/shot-peening-or-laser-peening/) but in specific cases an acceptable alternative. --- ### [Laser Peening](https://www.cwst.co.uk/home/services/laser-peening/) **Published:** August 20, 2015 **Author:** cwst_user **Content:** **Laser peening or laser shot peening can surgically place exceptionally deep residual compressive stress into key areas of a component to retard crack initiation and growth enabling increased fatigue strength ratings.** Laser peening is not a replacement for controlled shot peening but has additional advantages that can influence which method to use. ## Benefits of laser peening - Deeper residual compressive stress enabling better resistance to: - low cycle, high stress situations (LCF) - high cycle, low stress situations (HCF) in a deteriorating surface environment - erosion, strike damage, fretting and corrosion - Less cold work enables greater retention of residual compressive stress in high load and/or thermally challenging conditions - No process contamination - Original surface finish and topography easily maintained and controlled - Precision process and quality control ## Applications for laser peening Laser Peening is been used to prolong the fatigue life of critical aerospace components such as turbine engines and aircraft structures as well as for wing skins to achieve the requirements of the new generation of intercontinental aircraft. Laser peen forming essentially performs the same role as Peen Forming, but because of the greater depth of plastic work, extends the degree of curvatures possible enabling more fuel efficient profiles to be achieved. Potential applications of laser peen forming have also emerged for automotive, power generation, nuclear waste disposal, drilling, medical implants and recreational sports. ## Laser peening process [![Laser-Peening-diagram](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/08/Laser-Peening-diagram-1024x466.png?strip=all "Laser-Peening-diagram | CURTISS-WRIGHT SURFACE TECHNOLOGIES")](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/08/Laser-Peening-diagram.png?strip=all&w=2560) An output beam, roughly 25 Joules at 18 nanoseconds from a Nd:glass laser is projected onto a work piece to induce a residual compressive stress. The area to be peened can be covered with material to act as an ablative layer and simultaneously as a thermal insulating layer, or peened directly onto the base metal which subsequently may require some form of surface removal of a few microns. A thin stream of water is made to flow over the surface, the laser light transparently passes through the water and the leading temporal edge of the laser pulse is absorbed on the metal surface or ablative layer. This absorption rapidly ionizes and vaporizes more of the surface material to rapidly form a plasma that is highly absorbing for the rest of the laser pulse. A high plasma builds to approximately 100kBar (1 million pounds per square inch) with the water serving to inertially confine the pressure. This rapid rise in pressure effectively creates a shock wave that penetrates into the metal, plastically straining the near surface layer. The plastic strain results in a residual compressive stress that penetrates to a depth of between 1mm and 8mm depending on the material and the processing conditions. This deep level of compressive stress creates a damage tolerant layer and a barrier to crack initiation and growth, which consequently enhances the fatigue lifetime and provides resistance to stress corrosion cracking and fretting fatigue. ### **Laser peening of AI 6061-T6** [![Laser Peening Al 6061-T6](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/08/Laser-Peening-Al-6061-T6-300x144.jpg?strip=all "Laser Peening Al 6061-T6 | CURTISS-WRIGHT SURFACE TECHNOLOGIES")](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/08/Laser-Peening-Al-6061-T6.jpg?strip=all&w=2560)Multiple firings of the laser in a pre-defined surface pattern will impart a layer of residual compressive stress at and below the surface. The process can be tailored to suit the product and potential failure mechanism or enable higher potential loads through weight sensitive designs. The benefits of an exceptionally deep residual compressive layer are shown above. The S-N curve shows fatigue test results of 6061-T6 aluminium. The testing consisted of unpeened, [shot peened and laser](https://www.cwst.co.uk/home/shot-peening-or-laser-peening/) peened specimens. --- ### [IMR Test Labs - Mechanical Testing & Material Analysis Services](https://www.cwst.co.uk/home/services/material-testing-services/) **Published:** August 20, 2015 **Author:** cwst_user **Content:** **IMR Test Labs offer the latest in mechanical and metallurgical testing services including fatigue testing, material analysis services, thermal spray coating analysis, metallurgical and failure analysis.

Our controlled shot peening services are a cost effective and practical method of replacing tensile stress with beneficial compressive stress which is proven to prevent failures due to: - **Metal fatigue** - **Corrosion fatigue** - **Stress corrosion cracking** - **Intergranular corrosion** - **Fretting** - **Galling** - **Spalling** - **Wear** ## How shot peening is applied Controlled shot peening is a cold working process applied using spherical media known as shot. As each piece of shot hits the surface it creates an indentation where the surface will attempt to yield but is restrained by the substrate material. This conflict causes the substrate material to compress creating a beneficial compressive residual stress which makes the surface resistant to crack initiation and propagation and in the process removes any prior manufacturing tensile stresses. ![controlled shot peening diagram](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/08/controlled-shot-peening-diagram.png?strip=all "controlled shot peening diagram | CURTISS-WRIGHT SURFACE TECHNOLOGIES") ## Control and quality considerations for the shot peening process Each application is specified prior to processing which takes into account: [![Newbury-Auto-Impellor-CA-N](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/08/Newbury-Auto-Impellor-CA-N-240x300.png?strip=all "Newbury-Auto-Impellor-CA-N | CURTISS-WRIGHT SURFACE TECHNOLOGIES")](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/08/Newbury-Auto-Impellor-CA-N.png?strip=all&w=2560)geometry, manufacturing method, base material, strain sensitivity, in-service environment and loading conditions, as well as costs and turnaround time. When these parameters have been established, the required depth of compressive layer, choice and size of media, intensity and coverage and required surface stress will be calculated and tested, ensuring that any repeat work is carried out to the same specification as the original application. The majority of our controlled shot peening services are carried out using specialist robotic equipment which has been designed in-house, ensuring that the motion of the component to shot flow is consistent. --- ### [C.A.S.E Isotropic Surface Finishing Process](https://www.cwst.co.uk/home/services/c-a-s-e-vibratory-and-isotropic-super-finishing/) **Published:** August 20, 2015 **Author:** cwst_user **Content:** **The technique of C.A.S.E.™ (Chemically Assisted Surface Enhancement) isotropic superfinishing (also known as Isotropic Surface Finishing) has been developed as a metal surface treatment that provides components with excellent bending and contact fatigue strength with resistance to high loading.** ## How superfinishing works Controlled shot peening is followed by chemical surface isotropic finishing which gently removes any metal asperities but retains valleys for optimum oil retention, reducing surface friction and operating temperatures. ## **How the isotropic surface finishing process works** ![MIC Superfinish](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/08/MIC.Superfinish-300x230.jpg?strip=all "MIC Superfinish | CURTISS-WRIGHT SURFACE TECHNOLOGIES")The component is firstly [shot peened,](https://www.cwst.co.uk/home/shot-peening-or-laser-peening/) which is a cold working process creating multiple indentations in the surface using spherical media called shot. As each indentation is made, the surface will try to yield but is restrained by the substrate, introducing a residual compressive stress and removing any prior manufacturing tensile residual stresses. This isotropic superfinish technique makes the surface resistant to crack initiation and propagation. The intensity and coverage of the shot peening process is carefully specified prior to any work being carried out. Secondary processing by [shot peening](https://www.cwst.co.uk/services/shot-peen-forming/) (dual peening) at a lower intensity and modified shot size will have the effect of reducing surface roughness and increasing the compressive stress and cold working of the near surface providing additional benefit. Final machining is then carried out in a controlled and gentle manner using non-abrasive finishing stones together with oxalic acids where the most positive or peak surface areas are progressively removed producing a mirror-like surface finish. --- ### [Additive Manufacture (AM) Post Processing](https://www.cwst.co.uk/home/services/additive-manufacture-am-post-processing/) **Published:** January 31, 2020 **Author:** generateuk **Content:** Additive manufacturing is a rapidly growing industry, the technology has grown from a rapid prototyping solution into mainstream production of high complexity components.

Parylene is the generic name for a polymer series based on Poly-para-xylylene. Applied by vapour deposition process at room temperature this unique polymer creates an ultra-thin film highly lubricious and protective conformal coating. Parylene coatings conform to MIL-I-46058 Type XY, IPC-CC-830B and USP Class VI, and ISO 10993 approved for use as a medical biocompatible and implantable material. ## What does parylene coating do? Parylene ruggedizes electronic components and assemblies. It has excellent diametric strength, suppresses tin whisker growth, and significantly improves lead-free solder joint life. Chemically inert, ROHAS, and reach compliant, it encapsulates the product with a protective barrier, repelling corrosive chemicals, gases, moisture, and liquid. ## Is the parylene coating conformal? Stable for any substrate stable in a partial vacuum environment, regardless of the topography of the substrate, purity of the dimer, the deposition process ensures a truly conformal coating. ## What are the benefits of Parylene coatings? Parylene removes the tackiness of elastomeric parts without adding weight or materially affecting the substrate’s elasticity. Sealing porosity, [elastomers coated with parylene](https://www.cwst.co.uk/home/services/engineered-coatings/parylene-conformal-coatings/elastomers/) benefit from its low coefficient of friction, in addition to its biocompatible and environmentally protected layer. ## Are there different types of Parylene? While there have been many types of Parylene researched and developed over the past 40 plus years, Parylene N and C have the widest commercial use. Each has its own unique electrical and physical properties. ## What is the typical coating thickness? Typical coating thickness for lubricity of metal and plastic substrates is 3 to 5µm, while for silicone and rubber components 1 µm will significantly reduce tackiness. For chemical and moisture protection printed circuit boards and medical devices these are typically coated 6 to 25 µm depending on the specific purpose required. ## Does CW dimer for Parylene coatings differ from other dimer available on the market? Yes. CW dimer differs in purity. Our proprietary dimers are over 99.7% pure. Industry standard dimers are in the 93% range. The higher purity ensures a higher yielding [dimer and a Parylene coating](https://www.cwst.co.uk/home/services/engineered-coatings/parylene-conformal-coatings/cw-dimer/) that is clearer and more consistent in conformance to the substrate. ## Is parylene coating safe for the environment? Parylene is green chemistry, it produces no cut forces, no thermal stresses, or leachable ingredients. ## Can electronics be coated with parylene? Parylene is the coating of choice for high-reliability electronics. ## Can parylene be used for coating medical devices? For medical device manufacturing aids and delivery systems, parylene is used extensively to provide particulate-free bio-compatible dry-film lubricity. --- ### [Parylene Conformal Coatings](https://www.cwst.co.uk/home/services/engineered-coatings/parylene-conformal-coatings/) **Published:** August 20, 2015 **Author:** cwst_user **Content:** Parylene conformal coating is an ultra-thin film polymer coating that provides a uniform pin-hole-free barrier coating to all shapes, edges, crevices, and recesses with the same thickness without suffering any of the edge effects of conventional coatings.

It is the coating of choice to ruggedize critical electronics, devices and subassemblies in industries such as Aerospace, Defence and Medical. Parylene provides protection from moisture, corrosive bodily fluids, chemicals, gases, temperature and fungus far surpassing the protective properties of most other conformal coatings. **Solves dry friction** Parylene is a highly lubricous dry film coating. Parylene N has a low co-efficient of friction of 0.25 static and dynamic between 2.5 – 6µm. Being particulate free and bio compatible, it is the favoured dry film lubricant for release-ability of manufacturing aids for medical device manufacture. For elastomeric applications Parylene is used to remove tackiness from the substrate at coating thicknesses as low as 1500Å. ## Applications for Parylene coatings ## Medical Components and Solutions - Catheters - Mandrels - Sensors - Ultrasound transducers - Guide wires - Needles - Epidural probes - Elastomer components such as Silicone and latex components For medical devices requiring biomedical compatibility and barrier protection against biofluids, moisture and chemicals. Also acts as a dry film lubricant with a coefficient of friction measurement that approaches that of TEFLON®. Parylene type N is typically used in applications requiring this type of releasability or dry film lubricant. ## Electronic Components and Solutions - Circuit boards Even and consistent barrier coating which does not pull away from the edges or exhibit meniscus forces. Excellent dielectric strength. Resistant to humidity and practically insoluble in all known organic and inorganic solvents including acid and alkali. ## Wire Wound Device Components and Solutions - magnets - wire wound ferrite cores - powdered ferrite cores Elimination of abrasion damage to the wire along with uniform coating thickness Maximum winding window. Low water vapour transmission provides excellent corrosion protection. Eliminates magnetostrictive or permeability problems. ## Rubber Components and Solutions - Elastomer components - Rubber keyboard and controls Conforms to surface features including internal dimensions of holes. Strong surface adhesion and elasticity. Removes elastomer tack and protect against dirt, oils, petrochemicals and solvents. Protects printed legends from wear. ## Parylene Coating – Benefits - **Ultra thin lightweight film** – coating thickness of less than 1 µm can be applied, penetrating micro porosity to provide pin hole free protection and lubricity. - **Uniform** – thickness tolerances are typically held to ±20% from nominal.Tolerances as tight as ±5% are possible even for the most intricate and complex shapes. - **Stability** – Parylene is inert and insoluble in most solvent systems within its temperature range. It is thermally stable between -200°C and 125°C and higher in an inert environment. - **Dielectric strength** – extremely high dielectric strength of 7 kV/mil. - **Lubricant** – Parylene acts as a dry film lubricant, eliminating the need for liquid release agents. - **Environmental barrier protection** – Parylene provides protection from moisture, corrosive bodily fluids, chemicals, gases, temperature and fungus. - **Low stress process** – applied at room temperature. Any object which can be exposed to medium vacuum can be coated with Parylene. - **Elasticity** – elongation to break of Parylene C is 200%. - **Optical clarity** – Parylene C is optically clear. - **Sterilisation** – by any method has little impact to the physical properties of Parylene. - **FDA** – Device and Drug master file held with the FDA to support client company 510k submissions. ## Parylene Conformal Coating – Process - Parylene is applied at room temperature with specialized vacuum deposition equipment that permits control of the coating rate and thickness. - The deposition process takes place at the molecular level as the chemical, in a dimer form, is first converted into a gas under vacuum and heat; then it is pyrolized to cleave the dimer; and finally the monomer is deposited as a clear polymer film on all exposed surfaces in the deposition chamber. - The single coating builds up one molecule at a time, encapsulating any and all exposed surfaces. The material is applied at rates of 1 to 2 µm per hour. Coating thicknesses from 0.1 to 76 µm can be applied in a single operation. - Parylene will conform to any surface that is stable in a vacuum environment, regardless of the complexity of the geometry. - Parylene is applied in a gaseous state, so there is no risk for bridging, spotting or pooling as can occur with a liquid conformal coating. ## Parylene Coating Properties & Variants While there have been many types of Parylene researched and developed over the past 40 plus years, Parylene N and C have the widest commercial use. Each has its own unique electrical and physical properties. - Parylene conformal coatings are applied by vapour deposition under a vacuum in a coating chamber at room temperature. The Parylene coating process exposes objects to a gas-phase monomer at low pressure. Through vacuum deposition, Parylene condenses and polymerizes on the object’s surface in a polycrystalline formation. The Parylene coating grows at a rate 0.2µm – 0.3µm per minute depending on type N or C respectively. - Parylene C is most widely used as it has good electrical and physical properties. - Parylene N is selected for its high dielectric strength and where greater coating penetration is needed. Parylene conformal coatings are normally applied using a batch process where parts are put into a chamber, either horizontal (tumbler) or vertical. The batch process offers a cost-effective solution for many applications. ### CW Parylene N Type N or Natural, has the highest dielectric strength of these two commercial versions, and a dielectric constant value independent of frequency. It is able to penetrate crevices more effectively than type C because of the higher level of molecular activity that occurs during deposition. Parylene N is commonly used where lubricity is most needed and for high frequency electrical applications because of its low dissipation and dielectric constant values. ![](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2022/12/cw-parylene-n.jpg?strip=all "cw-parylene-n | CURTISS-WRIGHT SURFACE TECHNOLOGIES") ### CW Parylene C Parylene C differs chemically from N, having a chlorine atom on the benzene ring that results in a useful combination of electrical and physical properties including particularly low moisture and gas permeability. Parylene C deposits on substrates at a faster rate than Parylene N, and has a lower throw capability and an associated reduction in crevice penetration activity. Parylene C is commonly used for environmental protection. ![](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2022/12/cw-parylene-c.jpg?strip=all "cw-parylene-c | CURTISS-WRIGHT SURFACE TECHNOLOGIES") ### Other types of Parylene Coatings For applications operating continuously in air temperatures greater than 125°C other variants are available. However, the deposition rates for these higher temperature capability variants are significantly slower than those for Parylene N or C and the cost of application will increase proportionally. For the majority of commercial applications, Parylene N or C will be the logical choice. However, in some cases an alternative variant may be more appropriate. We can advise on the best route on specific projects once the end use requirements are assessed. ## Parylene Coating – Dimer Supplier Parylene raw materials are called dimers. CWST offers IPC-CC-830 and USP Class VI approved Parylene dimers. These are the key raw materials used in the Parylene coating process. The most common types of commercial [parylene raw material or dimers](https://www.cwst.co.uk/home/services/engineered-coatings/parylene-conformal-coatings/cw-dimer/) are Dimer C and Dimer N. [Read More >>](/home/services/engineered-coatings/parylene-conformal-coatings/cw-dimer/) --- ### [PTFE vs Parylene – Dry film lubricious medical coatings which is the better choice?](https://www.cwst.co.uk/home/services/engineered-coatings/parylene-conformal-coatings/ptfe-vs-parylene-dry-film-lubricious-medical-coatings/) **Published:** November 24, 2022 **Author:** cwst_user **Content:** When it comes solving non-release, dry sticking challenges most design and manufacturing engineers will have experience with PTFE and turn to it to solve their problems. PTFE has a lower co efficient of friction than Parylene. However in many cases application specific considerations make Parylene a better choice. ## Particulate PTFE which is a relatively hard coating around R58, it can be prone to chipping and flaking in certain conditions. The removal of PFOA (C8) from all PTFE used in Medical Device applications added further adhesion challenges. Reports of poor adhesion and delamination on stainless steel guide wires and other mandrel type products led to a number of voluntary recalls. As a softer polymer R80 Parylene in low friction applications will provide a higher yield or reusability and does not chip or flake in the same way PTFE does. Therefore where particulate is a risk Parylene may be a better choice. ## Complex typographies Parylene’s unique vapour deposition process provides for a truly conformal ultra-thin coating. For lubricity in mandrels the typical Parylene coating thickness is ≈ 4µm and as low as 0.15µm for elastomers. PTFE tends to be applied by spray or dip and can be prone to pooling, bridging and edge effect. Therefore Parylene is likely a better solution where dimensional tolerance is tight and with parts that are more complex in their topography. ## Mechanical wear Where there is good adhesion in both PTFE and Parylene mandrels, the PTFE being a harder coating, on the face of it would seem a better option. However wear characteristics depend on the application and operator use; comparative performance testing will provide the best information to make a long term choice for a specific application. While Parylene in low friction applications will provide a higher yield in high friction it will wear. For example, if tungsten were used for radiopacity in a peebax tip, when the peebax shrinks to a Parylene mandrel it will tear like sandpaper. PTFE rod in this case might be a better solution. In laser wielding applications Parylene significantly out performs PTFE which cracks and flakes within a short period of use. ## Sterilization methods Parylene’s properties are largely unaffected by any sterilization method. PTFE is unsuitable for Gamma and does not perform too well with Autoclave. Where Gamma is used ETFE will be a better choice for catheter lumen and in this case a Parylene coated introducer mandrel will compliment ETFE in release-ability. PTFE will not release from ETFE effectively. ## Manufacturing and coating process While PTFE is non-toxic, hydrofluoric acid and carbon dioxide are among the toxic byproducts of its manufacturing process. It also releases hydrogen chloride and other toxic substances at high temperatures. As PTFE cures at high temperature it is not suitable for heat sensitive substrates such as Nitinol. Parylene is a green chemistry. It is chemically inhert and non-toxic. It produces no leechable ingredients being free of catalytic, plasticizer and solvent residues. Parylene is applied at room temperature so it will be the natural choice with heat sensitive components and substrates. Find out more about [Parylene coating process](https://www.cwst.co.uk/home/services/engineered-coatings/parylene-conformal-coatings/). ## Cost Up front cost PTFE pre coated spool wire is cheaper and this tends to drive the decision in stainless steel single use mandrels. Though for longer bare wires, non-rounds and shaped parts this difference is diminished. In many cases where there is potential reuse Parylene will yield higher results reducing the overall unit cost. **Summary** The choice for a hydrophobic [medical coating](https://www.cwst.co.uk/home/services/engineered-coatings/parylene-conformal-coatings/medical/) will depend on the application and its specific considerations. Both Parylene and PTFE have their pros and cons. Where both seem a good fit a long term decision would benefit from comparative performance testing using the intended application rather than a paper only decision. --- ### [Register Form - Thank You](https://www.cwst.co.uk/home/contact-us/register/register-form-thank-you/) **Published:** March 16, 2023 **Author:** generateuk **Content:** Thank you for your message.

The growth of these hair like crystalline structures is a phenomenon that until recently was less of a concern. Before the RoHS Directive, the growth of tin whiskers was controlled very much by accident using lead solders; quite an effective suppressant. However the use of lead-free solders has seen the risk of tin whiskers become more prevalent.

Found in other metals such as Zinc, Cadmium, Indium, Aluminium and Silver the metal whisker can break off forming a bridge between two or more adjacent circuit elements causing them to short circuit. ## Protection with conformal coatings The application of a conformal coating can slow metal whisker growth but there are significant variations depending on the coating thickness and environmental conditions. For its ultra-thin coating thickness and truly uniform layer, Parylene surpasses other coatings in suppressing growth and insulating the rest of the assembly where a metal whisker has penetrated. Parylene is the coating of choice for mission critical electronics being applied in the medical market for pace makers, active implants and diagnostics equipment and for ground electronics and avionics systems used in the aerospace and defence markets. ## Parylene improves the life in Lead free solder joints In tests carried out by Curtiss-Wright Controls involving a range of conformal coatings, they found that under thermal shock testing involving continuous cycling between -40 and 125C, Parylene improved the joint life of lead free solder joints by an average of 200% that of any other coating tested. Parylene ruggedizes electronic assemblies, providing the reliability needed in critical applications; protecting from gases, chemicals, liquids and the risk of bridging posed by tin whiskers. ![Parylene coating for circuit boards](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2022/11/Parylene-circuit-board-300x176-1.png?strip=all "Parylene - circuit board | CURTISS-WRIGHT SURFACE TECHNOLOGIES")Parylene coating provides protection for circuit boards --- ### [Different removal methods for parylene coatings](https://www.cwst.co.uk/home/services/engineered-coatings/parylene-conformal-coatings/different-removal-methods-for-parylene-coatings/) **Published:** November 24, 2022 **Author:** cwst_user **Content:** ## Removal of Parylene coatings For high reliability electronics in many industries including Aerospace, Defence and Medical, Parylene coatings tend to be the first choice for environmental protection. However being highly resistant to chemicals, gases, liquids, temperature and electrical exposure does make removal and repair a challenge. ## Parylene Coating Removal Method – Thermal Removal While Parylene is heat-resistant, ‘C’ the most common variant for electronic applications will burn off where high temperature is concentrated. A soldering iron under a vacuum hood could be used to burn off at the solder points. Where it is raised from the board the component then lifts off. If the component is sitting tight to the board a blade could be used to carefully cut around the component to make removal easier.![](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2022/11/thermal-removal.jpg?strip=all&w=160) This might be effective for small repairs though it is not the cleanest method, residues and discolouration may result. As Parylene has a high melting point this approach could also pose a risk to heat sensitive substrates. ![](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2022/11/thermal-removal-1.png?strip=all&w=160) Laser ablation removes material from the surface by irradiating it with a laser beam. The beam can drill, cut or mark delicate materials with great precision. Laser ablation, removes very precise areas and tends to fit high density difficult to mask parts. Applications such as microelectronics, electro surgical devices and implantable electrodes that require very small, precise and intricate shapes to be Parylene free would be suited to this approach. It is less likely to be used for the purpose of general rework as it requires capital investment and specific programming that would not be viable for ad-hoc repair and rework. ## Parylene Coating Removal Method – Chemical removal Parylene is highly chemical resistant. No chemical can dissolve it are room temperature. However Tetrahydrofuran an organic solvent can soften the coating; temporarily loosening the adhesion bond between the coating and the substrate so that it can be lifted off like a mask with a tweezers. It is not suited to working with specific areas; in the case of rework and repair this is usually desired. ## Parylene Coating Removal Method – Mechanical removal ![](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2022/11/mechanical-removal-2.png?strip=all&w=160) Parylene is a soft polymer and as such physical, mechanical removal is probably the best method to remove the coating. Using coarse methods such as picking, scraping and cutting can be effective but risk damaging delicate track lines and components. ![](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2022/11/mechanical-removal-1.png?strip=all&w=60) The most common method to remove Parylene is micro abrasion. This is the fastest and easiest method for both spot and whole board removal. Desktop equipment can be used with a hand held stylus directing pressurized air and abrasive media. Wheat starch is the best for ESD sensitive boards; other common media include sodium bicarbonate and plastic beads. For finer control automated systems are also available. Once the section is repaired the specific area could be covered with other protective material however for optimum protection the whole board may be recoated in Parylene. --- ### [Adhesion Promotion](https://www.cwst.co.uk/home/services/engineered-coatings/parylene-conformal-coatings/adhesion-promotion/) **Published:** November 24, 2022 **Author:** cwst_user **Content:** Parylene can be successfully applied to almost any substrate, common materials include metals, elastomers, plastics, paper and glass. A key factor to this success is adhesion which can vary quite considerably unless the right pre-treatment procedures are followed. As Parylene adheres mechanically to the substrate cleanliness is the first step. The substrate must be free of contaminants. Many post manufacturing cleaning leaves residues, so a further cleaning process must be carried out so ensure coating adhesion can take place. These include sources such as mould release agents on plastic and elastomeric components and ‘no clean’ flux on PCBs. Once the parts to be coated are clean, the next step is to determine the correct adhesion promotion method. Where there is micro porosity in the surface such as with many elastomers or where a metal substrate has a high RA, little or no adhesion promotion may be required. However, most other substrates need adhesion promotion of some sort. ## Adhesion Promotion – Common methods **Mechanical abrasion:** This is where a very fine grit is used to lightly abrade metal surfaces therefore creating a mechanical key for the CW Parylene to attach to. This is commonly used in the production of Parylene coated wire mandrels, manufacturing aids used in the Medical Device industry. **Plasma activation**: As a pre-treatment this method activates the surface of many substrates including polymers, ceramics, glass and metals. As the activation is short lived this is usually carried out just before the coating process takes place. **Chemical bond pre-treatment:** The most commonly used silane solution for pre-treatment is A-174 which is applied by various methods including spray, dip and within the chamber by vapour deposition. CW Parylene’s adhesion can be greatly improved by pre-treating the surface in this way as it creates a chemical bond to the surface, improving the ability of CW Parylene to mechanically attach to the substrate. At Curtiss-Wright, we apply the most effective methods to clean and pre-treat the parts to ensure excellent adhesion, with thorough testing to ensure consistency of the results. We have proprietary silane’s that are specifically formulated to ensure excellent adhesion with more challenging substrates such as noble metals and many polymeric materials. Through our own development and external centres of excellence we continually strive to advance our adhesion promotion methods to handle the most challenging substrates, providing high reliability to customer applications operating in the harshest environments. --- ### [Curtiss-Wright Parylene Dimer Coating](https://www.cwst.co.uk/home/services/engineered-coatings/parylene-conformal-coatings/cw-dimer/) **Published:** November 24, 2022 **Author:** cwst_user **Content:** We can supply you with the same high quality Dimer that we use in our own coatings facilities. ## CW Dimer “The purest name in Dimer”™ Our proprietary dimers are over 99.7% pure, whereas industry standard dimers are only in the 93% range.

MIC jest wiodącą firmą w technologii kulowania, a dzięki ciągłemu wprowadzaniu nowych metod procesu technologicznego i unowocześnianiu wyposażenia, powodujemy znaczne zwiększenie zakresu zastosowania technologii kulowania. Obecnie, coraz nowsze gałęzie przemysłu stosują kulowanie w celu zapobiegania przedwczesnemu zniszczeniu lub dla osiągnięcia najlepszej jakości produkowanych wyrobów. Poszukiwanie nowych dziedzin zastosowania procesu kulowania, uprzednio nie brane pod uwagę, doprowadziło do rozwoju kulowania laserowego (patrz spis treści). Stawiamy na stały rozwój poprzez zrozumienie mechanizmów i celów procesu oraz stałą gotowość do dzielenia się naszymi osiągnięciami z partnerami na całym świecie.** Obecnie firma MIC znalazła uznanie w przemyśle lotniczym, samochodowym, chemicznym, wydobywczym, budowy okrętów, maszyn rolniczych i aparatury medycznej. Wiele spośród naszych zakładów otrzymało certyfikaty FAA, CAA oraz ISO 9002. Firma MIC ma ponad 30 zakładów w Stanach Zjednoczonych, Kanadzie, Wielkiej Brytanii, Francji, Niemczech, Belgii i Szwecji. Jesteśmy przygotowani do wykonywania usług w dziedzinie kulowania na rzecz naszych klientów w tych właśnie zakładach lub u klienta na całym świecie. Jesteśmy także przygotowani na dostosowanie naszego procesu do specyficznych potrzeb każdego klienta (na całym świecie) i na tym właśnie polega szczególna siła firmy MIC. Firma MIC znalazła swoje miejsce w dziedzinie obróbki cieplnej w 1979 r. i obecnie obsługuje liczne zakłady działające w tej branży w Stanach Zjednoczonych. Ponadto MIC produkuje uszczelnienia typu labiryntowego w swoim oddziale w Bloomfield, Connecticut. Te precyzyjne układy są używane w hermetycznie uszczelnionych kompresorach zamrażarek oraz w kompresorach samochodowych. ## Technologia Kulowania Kulowanie jest procesem obróbki na zimno, podczas którego ![polish-1](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/polish-1.jpg?strip=all "polish-1 | CURTISS-WRIGHT SURFACE TECHNOLOGIES")powierzchnia elementu jest bombardowana malymi okraglymi czastkami materialu zwanego srutem. Kazda drobina srutu, uderzajac w material, dziala jak mikroskopijne uderzenie mlotkiem powodujac na powierzchni malenkie wgniecenie lub wglebienie. Aby moglo powstac wglebienie, powierzchnia materialu musi ulec odksztalceniu (rozciagnieciu). Pod powierzchnia material próbuje powrócic do pierwotnego ksztaltu przeto wytwarza pod wglebieniem pólkule obrobionego na zimno materialu z wysokimi naprezeniami sciskajacymi. MIC ma przyjemnosc dzielic sie bogactwem swego doswiadczenia i wiedzy w dziedzinie kulowania poprzez swoja strone w sieci tak, aby inzynierowie i metalurdzy mogli dowiedziec sie o korzysciach wynikajacych z zastosowania technologii kulowania. Specjalisci MIC moga niesc pomoc w rozwiazywaniu wielu problemów technicznych, na które kulowanie ma zasadniczy wplyw. MIC posiada najnowsze wyposazenie umozliwiajace kulowanie czesci o róznych ksztaltach, rozmiarach i wykonanych z róznych materialów w scisle okreslonych i kontrolowanych warunkach. ![polish-diagram](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/polish-diagram-300x108.jpg?strip=all "polish-diagram | CURTISS-WRIGHT SURFACE TECHNOLOGIES")![polish-diagram2](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/polish-diagram2.jpg?strip=all "polish-diagram2 | CURTISS-WRIGHT SURFACE TECHNOLOGIES") Wiekszosc uszkodzen wywolanych zmeczeniem lub korozja zaczyna sie na powierzchni danej czesci. Zostalo stwierdzone, ze pekniecia nie powstaja i nie postepuja w glab materialu w strefie, w której wystepuja naprezenia sciskajace. Poniewaz zachodzace na siebie wglebienia (odksztalcenia plastyczne), powstale w wyniku kulowania, tworza jednolita warstwe z naprezeniami sciskajacymi na powierzchni metalu, proces kulowania w znaczacy sposób podwyzsza trwalosc obrabianych czesci. ciskajace naprezenia wlasne sa korzystne dla podniesienia wytrzymalosci zmeczeniowej, odpornosci na korozje zmeczeniowa, pekanie w wyniku korozji naprezeniowej, korozje wodorowa, korozje cierna (fretting), zatarcie i erozje powodowana kawitacja. Maksymalne naprezenia wlasne sciskajace wytworzone wskutek kulowania osiagaja maksymalna wartosc tuz pod powierzchnia czesci. Wartosci naprezen wlasnych sciskajacych sa przynajmniej tak duze jak polowa umownej granicy plastycznosci kulowanego materialu. Kulowanie jest takze stosowane do ksztaltowania aerodynamicznych krzywizn metalowych powierzchni skrzydel w zaawansowanym projektowaniu w przemysle lotniczym. Inne zastosowania to utwardzenie powierzchni poprzez obróbke na zimno w celu polepszenia charakterystyki zuzycia, zamykanie porowatosci, wzrost odpornosci na korozje miedzykrystaliczna, prostowanie znieksztalconych czesci, poprawianie tekstury powierzchni, sprawdzanie przyczepnosci pokryc.

Optymalne właściwości zmęczeniowe obrobionych części stalowych niekulowanych są uzyskiwane przy twardości 30 HRC (700MPa). Przy wyższych poziomach wytrzymałości/twardości materiały tracą wytrzymałość zmęczeniową z powodu wyższej wrażliwości na karb i kruchość. Po wytworzeniu w procesie kulowania ściskających naprężeń własnych wytrzymałość zmęczeniowa wzrasta proporcjonalnie do wzrastającej wytrzymałości/twardości. Np. przy twardości 52HRC (1240MPa ) wytrzymałość zmęczeniowa kulowanej próbki wynosi 988MPa (144 ksi), to znaczy wzrasta ponad dwukrotnie w stosunku do wytrzymałości próbki gładkiej, niekulowanej. ![polish1](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/polish1-300x215.jpg?strip=all "polish1 | CURTISS-WRIGHT SURFACE TECHNOLOGIES") Porównanie granicy wytrzymalosci kulowanych i niekulowanych próbek gladkich i z karbem w funkcji maksymalnej wytrzymalosci stali na rozciaganie. Proces produkcji – wpływ na wytrzymałość Faktem jest, iż procesy produkcyjne mają zasadniczy wpływ na właściwości zmęczeniowe wytwarzanych części. Wpływy te mogą być szkodliwe albo korzystne jak to obrazuje poniższy wykres: ## Wpływy szkodliwe ## Wpływy korzystne Hartowanie Nawęglanie Szlifowanie Honowanie (gladzenie) Skrawanie Polerowanie Pokrywanie Nagniatanie Spawanie Walcowanie EDM (obróbka elektroiskrowa) i ECM (obróbka elektrochemiczna) Kulowanie Wpływy szkodliwe takie jak szlifowanie, skrawanie, spawanie, powodują, że na powierzchni materiału powstają naprężenia własne rozciągające, co stanowi źródło pęknięć zmęczeniowych. Hartowanie, pokrywanie i EDM mogą wytworzyć powierzchnie bardzo kruche. Obróbka ECM może uszkadzać albo osłabiać powierzchnie granic ziaren. Procesy wymienione po stronie korzystnych podwyższają wytrzymałość zmęczeniową metali poprzez wartość wytworzonych ściskających naprężeń własnych. Kulowanie jest najskuteczniejszą obróbką ponieważ wprowadza największe ściskające naprężenie własne w największej ilości materiałów i przy różnych kształtach obrabianych części. Wykres prezentowany poniżej przedstawia krzywe w funkcji „s/n” (naprężenie w funkcji ilości cykli w stosunku do zniszczenia) dla różnego typu szlifowania. Krzywa odniesienia reprezentuje próbki delikatnie szlifowane o wytrzymałości 60 000 psi. Linia poniżej obrazuje zwykłe, fabryczne szlifowanie, w którym występują większe szybkości skrawania i usuwana jest grubsza warstwa materiału. W takim przypadku na powierzchni powstają naprężenia własne rozciągające o znacznej wartości, które mogą stanowić źródło pęknięć zmęczeniowych. Jak widać, wytrzymałość spada do 45 000 psi. Ostatnia krzywa przedstawia wytrzymałość próbek szlifowanych fabrycznie i kulowanych. Jak widać, wytrzymałość tych próbek znacznie wzrasta ponad krzywą odniesienia (próbek szlifowanych delikatnie) i przekracza wartość 80 000 psi. Naprężenia ściskające wytworzone przez kulowanie pokonują naprężenia rozciągające wywołane szlifowaniem. ![polish2](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/polish2-300x199.jpg?strip=all "polish2 | CURTISS-WRIGHT SURFACE TECHNOLOGIES") Korzyści te można rozpatrywać w kilku aspektach. Po pierwsze, kulowanie pozwala podnieść poziom naprężeń zewnętrznych przy tym samym poziomie wytrzymałości. Po drugie, kulowanie przedłuża żywotność każdej części przy przyjętym poziomie naprężeń zewnętrznych. Po trzecie, kulowanie pozwala na poszerzenie zakresu operacji produkcyjnych przez wprowadzenie pożądanych naprężeń ściskających. Kliknij na wykres w celu uzyskania powiekszenia. Kulowanie podwyższa wytrzymałość zmęczeniową szlifowanych elementów.

Uszkodzenia strukturalne wynikajace z SCC sa czesto nagle i nieprzewidywalne, moga nastapic po zaledwie kilku godzinach dzialania niekorzystnych warunków jak i po miesiacach a nawet latach prawidlowego dzialania. Spotkac sie z nim mozna nawet wówczas gdy nie wystepuje inne oczywiste znamiona korozji. Zasadniczo wszystkie rodzaje stopów sa podatne na SCC jesli sa poddane dzialaniu czynnika korozyjnego w specyficznym srodowisku korozyjnym. Naprezenia rozciagajace potrzebne do wywolania SCC sa „statyczne”; moga one miec charakter naprezen wlasnych lub zewnetrznych (patrz wykaz ponizej). Postepujace pekanie w wyniku „cyklicznych” obciazen w srodowisku korozyjnym jest okreslane jako „zmeczenie korozyjne”. Granica pomiedzy pekaniem w wyniku korozji naprezeniowej (SCC), a zmeczeniem korozyjnym jest czasem niewyrazna. Jednakze, (poniewaz warunki srodowiskowe, które je wywoluja, nie sa takie same) te dwa rodzaje uszkodzen sa traktowane jako oddzielne i odrebne mechanizmy pekania metalu. Naprezenia wlasne sciskajace, takie jak wywolywane w zewnetrznej warstwie struktury w procesie kontrolowanego kulowania, moga byc wykorzystane do zapobiezenia lub opóznienia obu tych zjawisk. ## WEWNETRZNE I ZEWNETRZNE ZRODLA NAPREZEN WYWOLUJACYCH SCC - spawanie - scinanie, wykrawanie (perforowanie), ciecie - zginanie, obciskanie, nitowanie - obrobka skrawaniem (tokarka, frez, wiertlo) - obrobka cieplna - EDM (obrobka elektroiskrowa), ciecie laserem/drutem - szlifowanie - odpuszczanie - wyzarzanie wahadlowe - rozszerzalnosc cieplna - drganie - ruch obrotowy - przesiewanie - cisnienie - obciazenie statyczne Pierwszorzedne znaczenie ma fakt, ze wytworzenie, w wyniku kulowania, sciskajacych naprezen wlasnych w powierzchniowej warstwie metalu moze byc skutecznym srodkiem przeciw SCC, niezaleznie od czynnika dominujacego, materialu czy osrodka korozyjnego. Jest to zobrazowane „trójkatem SCC”. Jesli którykolwiek z boków tego trójkata zostanie naruszony np. znikna powierzchniowe naprezenia rozciagajace, zjawisko SCC nie wystapi. **Korozja miedzykrystaliczna** Fotografia ponizej przedstawia powiekszenie mikroskopowe kulowanych i niekulowanych powierzchni probek ze stali nierdzewnej typ 304 (uwrazliwianej w 1200o F w ciagu 1h i sprawdzanej na wystapienie korozji miedzykrystalicznej w NH3-HF); kulowane kulkami ceramicznymi. Zgodnie z Polska Norma PN-ISO 3651-1 i PN-ISO 3651-2 zwiekszenie wrazliwosci stali uzyskuje sie zwykle przetrzymujac probke przez 30 min w temperaturze 700 10°C w srodowisku kwasu azotowego lub w roztworze kwasu siarkowego/siarczanu miedziowego. W Atomics International stwierdzono, ze mozna zapobiec wystapieniu korozji miedzykrystalicznej w austenitycznej stali nierdzewnej stosujac kulowanie przed poddaniem dzialaniu temperatury uwrazliwiajacej. W tym celu powierzchnia musi byc poddana obrobce na zimno – kulowaniu – w celu rozerwania ziaren powierzchni i granic ziaren. Poddane temperaturze uwrazliwiajacej wegliki beda raczej wytracac sie na wiekszosci miejsc krystalizacji (np. plaszczyznach uskokow, dyslokacjach) powstalych wsrod ziaren, a nie wzdluz ciaglych granic ziaren, co sprzyjaloby atakowi korozji miedzykrystalicznej w osrodku korozyjnym.

MIC heeft steeds het voortouw genomen in deze technologie, bij invoeren van procestechnieken, de installatietechnologie en bij de ontwikkeling van media waardoor het aantal toepassingen aanzienlijk is gestegen. Veel nieuwe industrieen gebruiken shot peening om voor vroegtijdige breuken te voorkomen of om het maximaal potentieel te bereiken dat bij het ontwerp werd voorzien. De zoektocht om dit proces uit te breiden in tot op heden onontgonnen gebieden, zet zich voort in de ontwikkeling van lasershot peening (zie inhoudstafel) We kennen een voortdurende ontwikkeling door het ontleden van het mechanisme en de doelstellingen van het proces en we zijn altijd bereid geweest deze kennis te delen met de betrokken partijen overal ter wereld.** MIC’s huidige kwalificaties overkoepelen vliegtuigbouw, ruimtevaart, automobiel, chemische, marine, landbouwkundige en medische industrieën. Daarenboven beschikken wij over FAA, CAA en ISO 9002 kwalificaties in de betreffende vestigingen. MIC beschikt over 30 shot peening divisies in de V.S., Canada, Verenigd Koninkrijk, Frankrijk, Duitsland, België en Zweden. Wij kunnen tegemoet komen aan bedrijfseisen via deze divisies of via werfopdrachten wereldwijd. Wij kunnen ook bedrijven lokaal assisteren ( waar ook ter wereld) met werfopstellingen om aan specifieke vereisten te voldoen, wat de kernsterkte is van MIC. MIC trad toe tot de commerciële warmtebehandelingen in 1979 en hedendaags opereren talrijke warmtebehandelings divisies in de V.S.A. Daarenboven, produceert MIC vingerkleppen in de Bloomfield, Connecticut divisie. Deze precisie kleppen worden gebruikt in hermetisch gesloten compressoren voor koelinstallaties en automobiel compressoren. ## Shot Peening Process [![test-pic](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/test-pic.jpg?strip=all "test-pic | CURTISS-WRIGHT SURFACE TECHNOLOGIES")](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/test-pic.jpg?strip=all&w=2560)Shot peening is een koud vervormingsproces waarbij het oppervlak wordt gehamerd met kleine ronde media (shot) . Elk kogeltje dat het oppervlak raakt, werkt als een kleine hamertje, die op het oppervlak een kleine inslag veroorzaakt wat ook een dimpel wordt genoemd.. Om deze dimple te creëren moet het oppervlak in spanning getrokken worden. Onder dit oppervlak, probeert het materiaal de oorspronkelijke vorm terug aan te nemen, waarbij onder de inslag een halve sphere wordt gevormd van koudvervormd materiaal met een hoge drukspanning. MIC is verheugd om zijn rijkdom aan kennis en ervaring te delen in shotpeening via onze website zo dat ingenieurs en metallurgisten zich bewust worden van de voordelen die shotpeening kan brengen. MIC engineering specialisten staan ter beschikking om te assisteren in de oplossing die shot peening kan brengen in menig engineering probleem. De MIC divisies gebruiken de nieuwste state-of the-art process mogelijkheden voor het shot peenen van component in diverse vormen, maten en materialen onder gecontroleerde condities. ![shotpeen-netherlands](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/shotpeen-netherlands-300x108.gif?strip=all "shotpeen-netherlands | CURTISS-WRIGHT SURFACE TECHNOLOGIES") ![shotpeen-netherlands](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/shotpeen-netherlands.jpg?strip=all "shotpeen-netherlands | CURTISS-WRIGHT SURFACE TECHNOLOGIES") Bijna alle vermoeiingss- en spanningsscheurcorrosie breuken ontstaan, aan het oppervlak van het stuk. Verder staat het vast dat scheuren niet zullen initiëren of zich voortzetten in drukspanningszones. Omdat de overlapping van de kogelinslagen een uniforme laag aanbrengen in drukspanning, levert dit proces een aanzienlijke verhoging van levensduur. Drukspanningen verhogen de weerstand tot vermoeiingsbreuken, corrosievermoeiing, spanningsscheur corrosie, waterstofbrosheid, fretting, koudlassen en erosie veroorzaakt door cavitatie. De maximum residuele drukspanning net onder het oppervlak is op zijn minst even groot als de helft van de treksterkte van het geshotpeende materiaal. Shot peening wordt ook gebruikt om aerodynamische vormgeving te induceren in metalische vleugelplaten (gebruikt in vliegtuigontwerpen). Aanvullende toepassingen waaronder het verharden door koudvervorming om slijtage te voorkomen, dichthameren van porositeiten, verbeteren van de weerstand tegen intergranulaire corrosie, rechten van vervormde stukken, aanbrengen van texturen en testen van de hechtingssterkte van coatings. Voor meer informatie over MIC en zijn diensten, [klik hier](http://maIlto:Kris_Maes@metalimprovement.com). ## Metaal vermoeiing De grafiek hieronder geeft de vermoeiingssterkte weer voor de maximum treksterkte voor gladde en gekerfde specimen. Zonder shotpeening , optimale vermoeiingseigenschappen voor bewerkte stalen componenten, worden verkregen op ongeveer 30 HRc (700 Mpa). Op hoger sterkte/hardheid niveau, verliezen componenten aan vermoeiingssterkte door het verhoogd kerfwerking en brosheid. ![netherlands1](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/netherlands1-300x213.jpg?strip=all "netherlands1 | CURTISS-WRIGHT SURFACE TECHNOLOGIES") Door toevoeging van drukspanning door shot peening, verhoogt de vermoeiingssterkte proportioneel met de verhoogde sterkte/hardheid. Als voorbeeld, bij een materiaalhardheid van 52 HRc (1240 Mpa), is de vermoeingsterkte na shotpeening 144 ksi ( 988 Mpa), meer dan het dubbel van een glad specimen zonder shot peening. Vergelijk van gepeende en ongepeende grenzen van een glad en gekerfd specimen, in fucntie van de treksterkte van staal Machine proces en hun effect op de levensduur. Machine processen zijn gekend voor hun beduidend effect op de vermoeiingseigenschappen van componenten. Deze effecten kunnen negatief of positief zijn en zijn onderverdeel hieronder ## Negatief ## Positief Harden Carburiseren Slijpen Honen Verspanen Polieren Coaten Ontbramen Lassen Walsen Vonk en electrochemisch verspanen Shot Peening Aan negatieve zijde, slijpen, verspanen en lassen induceren trekspanningen in het oppervlak als bronnen voor vermoeiingsscheuren. Harden, coaten en vonkverspenen laten een hard bros oppervlak na en chemisch verspanen kan de oppervlakte korrelgrenzen beschadigen of verzwakken. Aan positieve zijde dragen alle processen ertoe bij tot de verbetering van de vermoeiingslevensduur door het induceren van drukspanningen. Shot peening is de meest veelzijdige techniek daar het de hoogste hoeveelheid drukspanningen kan induceren op het meest diverse gamma van materialen en configuraties. De grafiek hieronder geeft de “SN” ( spanning tegenover aantal cycles) curve weer voor diverse slijpbewerkingen. De basislijn is voor zacht geslepen specimens en geeft een vermoeiingssterkte van 60.000psi. De “doorgedreven slijpen” curve ligt net daaronder en stelt een proces voor met snellere verspaningssnelheden en hoger aanzetten. Hierdoor worden hogere trekspanningen gegenereerd, opnieuw bronnen voor mogelijke vermoeiingsscheuren. Zoals voorgesteld, de vermoeiingssterkte daalt dan tot 45.000 psi. De laatste grafiek stelt de vermoeiingscurve voor bij een identiek proces als het laatste maar met toevoeging van shot peening. We bemerken dat de vermoeiingscurve de basiscurve beduidend overstijgt met een vermoeiingssterkte van 80.000 psi. . De geinduceerde drukspanningen hebben de trekspanning door slijpen beduidend geëlimineerd. Er bestaan verschillende manieren om deze voordelen te bekijken. Om te beginnen, shot peening laat een hoger spanningsniveau toe om de zelfde vermoeiingslevensduur van een component te bekomen. Ten tweede, indien het spanningsniveau ongewijzigd blijft, zal shot peening de levensduur beduidend verhogen en ten derde maakt shot peening het toelaatbaar te kiezen uit een groter aantal machine operaties, door de drukspanningslaag aan het oppervlak. ![netherlands2](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/netherlands2-300x182.jpg?strip=all "netherlands2 | CURTISS-WRIGHT SURFACE TECHNOLOGIES") ## Spanningsscheur corrosie ![stress-netherlands](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/stress-netherlands.jpg?strip=all "stress-netherlands | CURTISS-WRIGHT SURFACE TECHNOLOGIES")Spanningsscheur corrosie (SCC), is een zeer snel breuk mechanisme in metalen dat veroorzaakt wordt door de gelijktijdige interactie van een corrosieve omgeving en een toelaatbare trekspanning. . Structurele breuken, veroorzaakt door SCC zijn vaak onverwacht, het kan reeds op enkel uren na blootstelling optreden, of na maanden of zelfs na jaren van dienst. Vaak wordt SCC waargenomen op plaatsen waar geen enkele andere vorm van corrosieve aantasting bestaat. Virtueel zijn alle legeringen onderhevig aan SCC door een specifieke corrosieve omgeving in specifieke omstandigheden De trekspanningen nodig voor SCC zijn statisch en zij kunnen zowel residueel als toegepast zijn (zie tabel hieronder). Progressieve scheurvorming, ontstaan door cyclische spanningen in een corrosieve omgeving heet ” corrosie-vermoeiing”. De binding tussen SCC en corrosievermoeiing is soms heel vaag, desalniettemin , omdat de omgevingen waaruit ze ontstaan heel verschillend zijn, worden ze beiden als totaal verschillende scheurmechanismen beschouwd. Residuele drukspanningen, zoals die geinduceerd in de oppervlaktelagen van een geshotpeened oppervlak kunnen aangewend worden om beide phenomenen te voorkomen of uit te stellen. ## Spanningbronnen voor SCC ## Residueel ## Toegepast -Lassen -Thermische uitzetting -Afschuiven, ponsen en snijden -Thermische cycli, schrikken -Buigen, krimpen en klinken -Vibraties -Verspanen (frezen, boren) -Rotaties -Warmtebehandelingen -Bouten -EDM, Laser of draadsnijden -Druk -Slijpen -Dood gewicht Van primordiaal belang is het feit dat het induceren van residuele drukspanningen in het metaaloppervlak door shotpeening, een effectief middel is tegen SCC, geen rekening houdend met het dominant SSC mechanisme, het constructiemateriaal of de corrosieve omgeving. Dit wordt geillustreerd in de SCC driehoek. Indien één van de benen wordt verbroken, zoals door de afwezigheid van trekspanningen aan het oppervlak door shot peening, zal SCC niet optreden. Intergranulaire Corrosie Microscopische fotos van gepeend en ongepeend roestvrij staal 304 oppervlak ( ontlaten op 1200F gedurende 1uur en getest op intergranulaire corrosie in NH3-HF, peening met ceramische shot) Atomic International ontdekte dat intergranulaire corrosie in austenitisch roestvrij staal kan vermeden worden door shot peening voor het ontlaten in te voeren. Shot peening,moet door doorgedreven koudvervorming, de korrels en korrelsgrenzen breken waardoor bij ontlaten, de carbides kunnen precipiteren in de verschillende open plaatsen ( zoals dislocaties en schuifvlakken) die gevormd worden door de korrels, beter dan langs de korrelgrenzen die leiden tot intergranulaire corrosie in een corrosief medium. ![granular](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/granular-300x105.gif?strip=all "granular | CURTISS-WRIGHT SURFACE TECHNOLOGIES") links, gepeend ~~ recht, ongepeend MIC heeft tal van technische toepassingsrapporten gepubliceerd die op aanvraag beschikbaar zijn.

MIC è sempre stata all’avanguardia in questa tecnologia, introducendo nuovi processi, nuovi macchinari e sviluppando i “media” per nuove applicazioni (con il termine inglese media, si vuole indicare l’insieme delle caratteristiche del mezzo usato per pallinare, cioè forma, dimensione e materiale delle microsfere). Oggi, diversi settori industriali utilizzano la pallinatura controllata per prevenire rotture premature o per consentire ai progettisti di raggiungere il massimo potenziale dei materiali. La ricerca per estendere questo processo ad aree precedentemente non contemplate continua con lo sviluppo del Lasershot peening, cioè la pallinatura controllata effettuata con impulsi laser (rif. home page in inglese). Abbiamo ottenuto continui miglioramenti tramite lo studio e la comprensione del processo e siamo sempre stati disposti a mettere a disposizione le nostre conoscenze con ogni controparte interessata in tutto il mondo.** MIC opera attraverso più di 60 stabilimenti negli Stati Uniti, Canada, Inghilterra, Francia, Germania, Belgio, Svezia, Spagna, Irlanda e Cina. Ogni stabilimento ha certificazioni che coprono i settori aerospaziale, automobilistico, chimico, marino, agricolo, estrattivo minerario e medicale. Siamo preparati a soddisfare le esigenze di qualsiasi azienda in tutto il mondo attraverso questi stabilimenti o, per lavorazioni specifiche presso il cliente. Siamo altresì pronti ad assistere localmente una azienda (sempre in tutto il mondo) con impianti appositamente studiati e dedicati. Oltre ai processi di pallinatura controllata e pallinatura laser, MIC si occupa da molti anni di formatura/correzione di forma mediante pallinatura e di trattamenti termici. Recentemente opera anche nel campo dei rivestimenti speciali (coating). E’ possibile consultare l’indice a fianco per informazioni base sulla pallinatura controllata, o la versione in inglese del sito con informazioni più dettagliate. E’ altresì possibile scaricare una copia del manuale “Guida alle Applicazioni della Pallinatura Controllata”, che fornisce sia nozioni teoriche che possibili applicazioni della pallinatura, riportando anche diversi esempi pratici. ## La Pallinatura Controllata La pallinatura controllata, in inglese shot peening, è un processo di [![test-pic](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/test-pic.jpg?strip=all "test-pic | CURTISS-WRIGHT SURFACE TECHNOLOGIES")](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/test-pic.jpg?strip=all&w=2560)lavorazione a freddo in cui la superficie di un pezzo è bombardata con microsfere (shots). Ogni microsfera, colpendo il pezzo, agisce come un piccolo martello, lasciando sulla superficie del materiale una piccola impronta. Perché si crei l’impronta, la superficie deve subire uno snervamento a tensione. Sotto la superficie, il materiale tenta di recuperare la sua forma originale, creando così, sotto l’impronta, un emisfero di materiale lavorato a freddo fortemente sollecitato a compressione. MIC è felice di condividere la sua esperienza e competenza nella pallinatura controllata attraverso il suo sito web cosicché progettisti e metallurgici possano essere coscienti degli effettivi benefici che la pallinatura può portare. I nostri tecnici sono a disposizione per assistenza in tutti quei casi in cui problemi progettuali possano essere risolti con la pallinatura controllata. Gli stabilimenti MIC usano i più recenti macchinari e i più sofisticati processi per pallinare in condizioni strettamente controllate componenti di diverse forme, dimensioni e materiali. Quasi tutte le rottura a fatica o per corrosione sotto sforzo hanno origine sulla superficie del pezzo. Inoltre, è ben noto che le cricche non hanno inizio o comunque non si propagano in una zona sollecitata a compressione. Poiché il sovrapporsi delle impronte ottenute con la pallinatura crea uno strato uniforme di sollecitazione a compressione sulla superficie del metallo, il processo della pallinatura controllata permette un incremento significativo della vita di un particolare meccanico. Sollecitazioni a compressione consentono di aumentare la resistenza a rotture per fatica, a rotture per fatica in ambiente aggressivi, a rotture per corrosione sotto sforzo, a formazione di cricche facilitate da idrogeno, a corrosione da attrito, a galling, a erosione per cavitazione. La sollecitazione residua a compressione ottenuta immediatamente sotto la superficie del particolare sottoposto a pallinatura è come minimo la metà del carico di snervamento caratteristico di quel particolare materiale. La pallinatura controllata è usata anche per creare la curvatura aerodinamica delle lamiere metalliche delle ali degli aeroplani. Inoltre, viene anche usata per chiudere le porosità, aumentare la resistenza a corrosione intergranulare, per raddrizzare particolari precedentemente deformatisi a causa di lavorazioni, per finitura superficiale, per testare la forza del legame chimico di rivestimenti e per indurire con lavorazione a freddo un materiale e per aumentarne la resistenza ad usura. ## La Resistenza a Fatica Il grafico sotto riportato confronta la resistenza a fatica con il carico di rottura di provette sia con intaglio che levigate. Senza la pallinatura controllata, proprietà a fatica ottimali per componenti in acciaio lavorati a macchina, si ottengono a circa 30 HRc (700 MPa). Con carichi o durezze maggiori, i materiali perdono in resistenza a fatica a causa della maggiore fragilità e sensibilità agli intagli. Con l’introduzione di una sollecitazione a compressione indotta dalla pallinatura controllata, la resistenza a fatica aumenta in modo proporzionale all’aumentare del carico di rottura o della durezza. Per esempio, a 52 HRc (1240 MPa), la resistenza a fatica delle provette pallinate è 993 MPa (144 ksi), più del doppio della resistenza a fatica delle provette lucidate ma non pallinate (vedasi grafico; si è preso in considerazione un numero di cicli pari a 2 milioni). ![italian2](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/italian2-300x214.jpg?strip=all "italian2 | CURTISS-WRIGHT SURFACE TECHNOLOGIES") Confronto tra limiti di resistenza a fatica per provette in acciaio (lucidate dopo la lavorazione meccanica o al naturale) con o senza pallinatura controllata, come funzione del carico a rottura dell’acciaio stesso. Lavorazioni – Effetti sulla resistenza a fatica E’ risaputo che diverse lavorazioni hanno un effetto significativo per la resistenza a fatica di particolari meccanici. Tali effetti possono essere negativi o positivi, come riportato nella tabella sotto: ## Negativi ## Positivi Tempra Cementazione carburante Rettifica – Molatura Levigatura Lavorazioni a macchina Lucidatura Laminatura Brunitura Saldatura Rullatura Elettrorosione e Lavorazioni Elettrochimiche Pallinatura Per quanto riguarda gli effetti negativi, rettifica, lavorazioni meccaniche e saldature possono lasciare la superficie del pezzo con tensioni residue, invito per la rottura a fatica. Tempra, laminatura e elettrorosione possono rendere fragile la superficie. Le lavorazioni elettrochimiche possono danneggiare o indebolire i legami tra i grani superficiali. Per quanto riguarda gli effetti positivi, tutti i processi elencati aumentano la resistenza a fatica grazie allo strato di compressione superficiale residua che inducono. La pallinatura controllata è il più efficace tra tutti poiché induce una maggiore sollecitazione a compressione nella maggiore varietà di materiali e con le più svariate forme geometriche. Il grafico sotto riportato riproduce alcune curve “s/n” (stress / number of cycles, sollecitazione / numero di cicli prima di rottura) per parti sottoposte a diversi tipi di intaglio. La curva base, in blu, è quella per provini con “intagli piccoli” e mostra un carico limite a fatica di circa 414 MPa. La curva rossa rappresenta il comportamento di provette con intagli ottenuti con maggiore velocità e/o di dimensioni maggiori: in questi casi, vengono generate tensioni residue più alte. Come si può leggere dal grafico, carico limite diventa circa 310 MPa. La curva verde, per provette con intagli di qualsiasi genere ma pallinate, evidenzia un carico limite a fatica di circa 585 MPa. La sollecitazione a compressione indotta dalla pallinatura controllata è maggiore della sollecitazione a trazione causata da intagli severi. Questi benefici possono essere letti in diversi modi. Primo, la pallinatura controllata consente ad un componente un ugual numero di cicli anche se sottoposto a maggiore sollecitazione. Secondo, a parità di sollecitazione, la pallinatura aumenta la vita utile di qualsiasi componente. Terzo, la pallinatura consente di ricorrere ad un numero più elevato di lavorazioni grazie alla sollecitazione a compressione indotta. ![italian](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/italian-300x202.jpg?strip=all "italian | CURTISS-WRIGHT SURFACE TECHNOLOGIES") Cliccare sul grafico per aumentarne le dimensioni. La pallinatura controllata aumenta il limite di fatica. ## Rottura per Corrosione sotto sforzo ![SCC_Diagramsmall](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/SCC_Diagramsmall.jpg?strip=all "SCC_Diagramsmall | CURTISS-WRIGHT SURFACE TECHNOLOGIES")La rottura per corrosione sotto sforzo (o tensocorrosione; in inglese “SCC”, “stress corrosion cracking”) avviene per un meccanismo di frattura progressiva nel metallo causato dalla interazione simultanea di un mezzo aggressivo e di uno sforzo a trazione. Cedimenti strutturali dovuti a SCC sono spesso improvvisi e non prevedibili e possono verificarsi dopo poche ore o addirittura dopo mesi o anni. Praticamente tutte le leghe, in presenza di particolari condizioni e di un ambiente corrosivo specifico, sono suscettibili a cedimenti per corrosione sotto sforzo. La rottura per corrosione sotto sforzo si verifica con sollecitazioni costanti a trazione, siano esse residue o/e applicate (vedi tabella sotto riportata). Cedimenti progressivi causati da sollecitazioni cicliche in ambiente corrosivo vengono definiti come “rotture a fatica in ambiente corrosivo”. Il confine tra rottura per corrosione sotto sforzo e rottura a fatica in ambiente corrosivo non è ben definito; comunque, poiché le condizioni ambientali che li causano non sono le stesse, i due tipi di cedimento sono considerati come due meccanismi di frattura del metallo separati e distinti. Sollecitazioni residue a compressione come quelle indotte sugli strati superficiali di un particolare meccanico dalla pallinatura controllata, possono essere usate per prevenire o ritardare entrambi i fenomeni. ## SCC: Fonti di sollecitazione ## Residua ## Applicata – Saldatura -Tempra -Tranciatura, Punzonatura, Taglio -Cicli termici -Piegatura, Orlatura, Rivettatura -Espansioni termiche -Taglio a laser e a filo -Vibrazioni -Lavorazioni meccaniche (Tornitura, Foratura, Fresatura) -Imbullonatura -Elektro-erosive Bearbeitung (Laser/Drahtschneiden) -Verbolzung -Tattamenti Termici -Pressioni -Rettifica -Carichi applicati Di primaria importanza è il fatto che uno stato di compressione residua, indotto sulla superficie del materiale dalla pallinatura controllata, può essere un mezzo efficace per prevenire la rottura per tensocorrosione qualunque sia il meccanismo di tensocorrosione stessa predominante, il materiale della struttura o qualunque sia l’ambiente esterno causa della corrosione. Ciò viene spiegato con il “triangolo SCC” (vedi figura): eliminando un lato del triangolo, nel nostro caso la tensione superficiale tramite la pallinatura controllata, il fenomeno della rottura a tensocorrosione non avrà più luogo. Corrosione Intergranulare Microfotografia di un particolare della superficie di un piatto in acciaio inossidabile AISI 304 con e senza pallinatura controllata (sensibilizzato a 650 °C per un’ora e testato per corrosione intergranulare in NH3-HF, pallinatura con ceramica). E’ stato scoperto all’Atomics International che la corrosione intergranulare può essere prevenuta nell’acciaio inossidabile austenitico attraverso la pallinatura controllata prima che il materiale sia sottoposto a temperature di sensibilizzazione. A questo scopo, grazie alla pallinatura controllata, la superficie subisce un processo severo di lavorazione a freddo così da rompere i grani superficiali e il bordo dei grani stessi. Quando esposti alla temperatura di sensibilizzazione, i carburi precipitano sui numerosi siti di enucleazione (piani di scorrimento, dislocazioni) che si sono formati all’interno dei grani anziché lungo i loro bordi, limitando così la corrosione intergranulare in ambienti corrosivi. ![granular](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/granular-300x105.gif?strip=all "granular | CURTISS-WRIGHT SURFACE TECHNOLOGIES") Sinistra: Pallinato ~~ Destra: Non Pallinato --- ### [Shot Peening Specifications](https://www.cwst.co.uk/home/downloads/approvals-and-specifications/shot-peening-specifications/) **Published:** October 28, 2015 **Author:** generateuk **Content:** Customers usually require the [shot peening process](https://www.cwst.co.uk/services/controlled-shot-peening/) to be carried out in accordance with industry specifications, ensuring that the process is quality controlled, repeatable and that strict criteria has been met. Some larger companies have designed their own company specifications that cater for their specific requirements but for smaller operators their engineers usually specify the industry standard specifications on drawings or callouts. Most shot peening standards and specifications are administered by a specialist body called the SAE (formerly known as the Society of Automotive Engineers) and two of the SAE categories that apply to shot peening standards are those prefixed by AMS (Aerospace Material Specification) and J which relate to ground vehicles and general applications (they can also be used for aerospace). In addition to SAE you will also find military specifications are commonly used alongside those written by shot peening specialists such as Metal Improvement Company and those are prefixed by MIL and MIC respectively.

The removal of surface tensile stresses or reduction below threshold levels can eliminate stress corrosion cracking. **Wear** This can be reduced by improving friction characteristics and increasing mating hardness. **Welding** Heat generated by the welding process will often produce tensile stresses which contribute to poor fatigue characteristics --- ### [Superfinition Isotrope C.A.S.E](https://www.cwst.co.uk/home/francais-accueil/superfinition-isotrope/) **Published:** November 5, 2015 **Author:** generateuk **Content:** **Le procédé C.A.S.E.™ (Chemically Assisted Surface Enhancement) a été développé e particulier pour les engrenages et les cages de roulement afin d’optimiser les propriétés de résistance aux phénomènes de Fatigue et de Pitting.** Le procédé consiste en un Grenaillage de précontrainte, suivi d’une finition isotrope pour étendre la limite de fatigue en surface au-delà de celle obtenue par simple grenaillage. ## Avantages - Procure un état de surface proche du poli miroir - Réduit les temps de fabrication et les coûts de production - Finition compatible avec le nettoyage et la stérilisation microbiologiques - Améliore la rugosité et augmente les contraintes admissibles - Réduit l’endommagement au Pitting - Augmente la rétention de lubrifiant - Permet le cassage d’angles et facilite la manipulation et l’assemblage - Diminue la température des lubrifiants - Réduit les bruits dans les transmissions ## Applications ![off-road](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/off-road.jpg?strip=all "off-road | CURTISS-WRIGHT SURFACE TECHNOLOGIES")Le procédé CASE s’applique sur les dentures en complément du traitement thermique après usinage ou rectification et permet d’obtenir une meilleure lubrification à flancs de dents par la suppression des aspérités de surface. Ce procédé a fait ses preuves sur les transmissions, les clapets et les boîtes de vitesse utilisées dans l’aéronautique, l’éolien, l’automobile, les véhicules tous terrains et de terrassement. La durée de vie les pièces traitées sera notablement prolongée. Destiné à toutes les pièces sollicitées au ![gears](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/gears.jpg?strip=all "gears | CURTISS-WRIGHT SURFACE TECHNOLOGIES")roulement et au glissement métal contre métal, toutes les tailles d’arbres de transmission ou de pignons peuvent être virtuellement traitées. Notre retour d’expérience du procédé CASE sur des pignons a démontré une durée de vie multipliée par 5 avant l’apparition des premiers signes d’écaillage (Pitting). Une référence en compétition automobile a notamment mis en évidence l’absence de micro-écaillage (Micro-Pitting) après 3 courses. - Pièces de transmission - Roulements - Cames et galets suiveurs - Paliers - Plans de joint - Toutes situations impliquant un contact métal contre métal ## Grenaillage de Précontrainte ![influence de la charge appliquée - somme algébrique](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/grenaillage.jpg?strip=all "grenaillage | CURTISS-WRIGHT SURFACE TECHNOLOGIES")Influence de la charge appliquée somme algébriqueUn [grenaillage contrôlé](https://www.cwst.co.uk/francais-accueil/le-grenaillage-de-precontrainte/) est un bombardement de la surface avec un petit média sphérique ou “billes” dont la taille et la qualité sont prédéfinies et contrôlées. Les billes peuvent être en acier, inox, verre ou céramique. Chaque bille frappe le métal tel un petit marteau créant une empreinte en surface. L’incidence de ces déformations génère des contraintes résiduelles de compression par un allongement dans le domaine élasto-plastique en surface et une réaction du matériau à cœur. L’amplitude de la contrainte résiduelle de compression est directement liée à la limite d’élasticité du matériau et est de l’ordre de 80% de cette valeur. Les contraintes résiduelles de traction d’usinage sont éliminées, prolongeant ainsi la durée de vie. Un double grenaillage (Dual Peening) avec une intensité plus faible et une taille de bille plus petite réduira la rugosité et augmentera la contrainte en surface, l’écrouissage apportant un bénéfice supplémentaire. ## Superfinition Isotrope ![finition-isotrope](https://ekfvrb285nz.exactdn.com/wp-content/uploads/2015/11/finition-isotrope.jpg?strip=all "finition-isotrope | CURTISS-WRIGHT SURFACE TECHNOLOGIES")La finition isotrope supprime les aspérités en surface tout en préservant l’intégrité de la couche mise en compression. De plus elle laisse quelques empreintes (ou vallées) issus du grenaillage ou de la rectification, vitaux pour la rétention du lubrifiant. Cette modification de surface permet le maintien uniforme d’un film lubrifiant tout en réduisant sa température et les frictions. Il en résulte une diminution des pertes de puissance et une amélioration des performances et de la durée de vie des transmissions. Cette technique de finition est douce et maîtrisée par l’utilisation d’un acide oxalique et d’un média non-abrasif. L’action de l’acide oxalique fragilise les pics (ou sommets) qui sont progressivement aplanis par micro-rodage. Après une durée prédéterminée, la phase chimique est stoppée suivie d’une phase de rinçage/polissage qui ralentit progressivement la formation d’oxydes et produit un effet poli-miroir en surface. La formulation chimique spéciale n’attaque ou n’érode ni la surface ni la structure granulaire du matériau. Toutefois la courte durée du processus rend possible une production pour de grands volumes de pièces. Les médias de finition isotrope sont sélectionnés afin de porter sur les pics de rugosité d’usinage et ne pas enlever les vallées utiles pour la rétention du lubrifiant. L’écaillage (Pitting Fatigue) est un facteur critique dans l’analyse de charge qui limite la conception de la plupart des pignons. La superfinition CASE a démontré son efficacité dans le retardement de l’apparition du macro ou micro-pitting. L’amélioration de l’état de surface permet une meilleure répartition de charge en réduisant la pression de contact et augmente la durée de vie. --- ## Categories ### [Uncategorized](https://www.cwst.co.uk/category/uncategorized/) **Description:** Have a look at our latest blog posts for insights, news and tips. --- ### [Archived News](https://www.cwst.co.uk/category/archived-news/) **Description:** Read our blog posts and articles for news, insights and tips on engineered coatings and more. --- ### [Company](https://www.cwst.co.uk/category/company/) **Description:** Company news for Curtiss-Wright Parylene Coatings --- ### [Events](https://www.cwst.co.uk/category/events/) **Description:** Curtiss-Wright Parylene Coatings Events and Exhibitions --- ### [News](https://www.cwst.co.uk/category/news/) **Description:** Latest News From Curtiss-Wright Surface Technologies --- ### [Technical](https://www.cwst.co.uk/category/technical/) **Description:** Technical news for Curtiss-Wright Parylene Coatings ---
